My point is that I just want to be able to discuss any topic with my followers without self-policing lest a bunch of anonymous accounts butts into the conversation and completely derails it.

What you're probably looking for is closer to a closed discussion group or mailing list than "social media", which is presently universally-readable, algorithmically-targeted, feed-based, advertising-supported, and increasingly, saturated with AI slop (which itself has replace clickbait and ragebait).

Which reminds me of Kitman's Law: Pure drivel tend to drive off the TV screen ordinary drivel.

I want my posts universally-readable and universally-interactable (that's why I don't like the idea of locking my accounts). I also want to be able to explore the social graph — looking at who follows who, what that friend of a friend posts, etc. It all forms an integral part of what social networks are.

What I absolutely do not want is the platform having any of its own agency. I want a social network that ideally works as a dumb pipe. I especially don't want my content surfaced in front of the kinds of people who would've never found it through their own exploration.

It should come as no surprise, then, that I have a lot of faith in the fediverse.

Twitter has settings for who can reply to tweets, which are configurable per post. You can make it so that only people you follow can reply.
