Great suggestions among your list! This one I like in particular: I can see so many ways to use this, no only regarding sensitive content, but also including "shadow banning".

Updated #13 🔽
13. Inactive members.
13.1. Feature to automatically delete inactive members for the period of time.I don't want dead souls on board and make illusion for members that we have thousands active members. So better to make feature to set a timeframe for inactive members after that they can be automatically deleted from the community.
13.2.  Option to show members not agreed with updated and forced Terms & Rules. Or automatically deletion disagreed members feature.

I want my community to be the income oriented platform and professional profit focused ecosystem. The below features are the tools to achieve mentioned goal:
CONTENT
1. Allow Administrator to change the TopicStarter (Author).
Some Authors can be banned or deleted from community, but topic can be popular and deserves to stay.
2. Option to limit members from change topic title and first message separately.
Most members creating misspelled topic titles and Administrator can edit more correct and SEO-friendly.
3. If Reply to this status..., then updated status goes UP in All Activity feed and in Members own feed.
Improves moderation and in profiles activity.
4. Share this post on other sites: Add WhatsApp, Telegram, WeChat, Instagram, Tumblr, VK, XING. + Add the setup option for this feature in the AdminCP.
5. Display icons on Pinned topics and Recommended posts in All Activity feed.
6. Built-in translator for messages in other languages.
7. Members can Pin own message on its Profiles Activity feed.
8. Auto-width size of Excel table after copy-paste.
9. If Delete All Content (Members) then delete created Clubs too.
If I want to delete all the content of specific user, It should be erased completely! No need ghost-clubs, except the Public ones.
ECOSYSTEM
10. Setup permissions for members group that way, so the members of "one group" could see each other content, but other groups can't see "one group" content. Like parallel world in the same community. + Hide "one group" content from search engines.
Within the framework of freedom of speech, that is a good feature to hide and allow sensitive content.
11. Option to leave the community. Ex.: Member leaved the community N minutes ago
Sometimes Members asks to delete their account. Let them do it ourselves. And let them to decide in deletion menu to stay posted content as Guests or Delete All Content. 
12. Set up premium buttons for Members to pay for extra options on direct pages: pin topic, change members group, recommend post, promote.
Admin pre moderation.

WORD FILTERS
14. Word Filters for About Me in profiles, Usernames, Tags.
Unfortunately Members can still avoid and post inappropriate content in mentioned sections.
15. If Added new word to filter, all the filtered content must be updated regarding Action to take.
Before I added another word to filter there is still hundreds of active topics and thousand active messages with the banned word.
16. When any content is hidden for moderation approval on the Words Filter basis, highlight the banned words for Administrator.
It needs a lot of time for moderator\admin to understand why the message was filtered: hard to find a filtered word in long texts.
17. Text Editor for Replace with text action in Word Filters. Ability to chage color for replaced text.
Amex credit card holders Indian or any country cards can be filtered word.
Amex credit card holders Indian or any country cards can be filtered word.
To pay more attention to the rules for intruders.
18. Add new action to take: Hide\Reveal objectionable word.
Instead of replacing text create to hide the objectionable word instead and a user simply places their mouse cursor over the top of it to reveal the word.

The objectionable word is still present just obscured from view unless someone chooses to reveal it. 

Going to go through the rest of the list, but this one is great. There's a plugin for it. I use it in my own community 👍 
It's for 4.5 but from what I gather it should work for 4.6. Haven't tried it yet though so don't take my word for it 😆 
 

10. Feature color in profile's topics section.
community.com/profile/member/content/?type=forums_topic&change_section=1
Featured by color topics are still off and #000000 by default in the profile's topics section.

This seems a bit situational? I have never had this need, but I can see the need for it. Not sure if it should be in core or as a plugin though. Probably a plugin is better? I like it. +1 Plugin for sure. +1 Plugin. +1 Never seen anyone paste an excel to be honest. Can it be solved using CSS maybe? I think that need some considerations, since it is not always that you want to remove clubs just because you want to remove someone's content. I see other ways to limit spambots for example that is probably better, but I see that there are situations it could be useful. I would say plugin though. I think this already exist, or maybe I misunderstood the concept. If it does not exist I would say plugin (because I did not understand it then  and I am evil that way). Plugin I think... Plugin. Could be useful I guess. I'll give it a +1. Sounds a a bit excessive, but maybe if there is a lot of people needing it? You want a feature that pushes changes to TOS so every single member must agree again or be deleted? Sounds situational and probably best as a plugin? +1 A recursive filter when adding banned words. I though we already had that, but if not...+1 +1. With #17 below, this would already be taken care of, right? Depending on how many banned words you have you can do this manually, but adding a class to it so you can manage easier is  good suggestion. +1 Can be managed if #17 is added.  
Not writing this to shut down any of your suggestions, just giving my thoughts on what might be better as plugins so you can dig deeper into that to get the community you want.
