A good place to find Mastodon instances is on the official Mastodon website's communities section:
They are organised by topic, and all of the instances on the list have to agree to a covenant covering reliability and responsible moderation (https://joinmastodon.org/covenant).
(There are thousands more instances out there beyond this list, but this list is probably the surest and best starting point. Also, you can set up your own if you prefer.)
If you're on a big instance with lots of members, you might want to consider moving to a smaller instance.
Smaller instances can give members more personal attention, as the admin has more time to deal with members' feedback. They also tend to have more interesting local timelines if you pick an instance that matches your favourite topic.
Using smaller instances also protects the Fediverse from nasty people or companies, because a spread-out Fediverse is much harder to hack or buy.
You can keep your followers and follows. I've linked to advice on how to do this earlier in this thread.
You can't keep your posts.
@feditips Our signups are open, for anyone that might be thinking of doing that! Sure, it's an instance mostly populated by visually impaired people right now, but it's not meant to be just for those, so unless that bothers you for ... some reason, feel free to join if you like the vibe!
You can read our rules here: https://dragonscave.space/about/more
For example jako.social is open for registration. I cannot add this instance to the official list since I the second moderator I have isn’t very active and the official list requires two moderators. This instance is also proxied trough Cloudflare and hosted on Hetzner.
I tried to add this instance to the instances.social list but you can read more about this on the instances.social git issues.
So far I have fully working, well set up instance but no way of ”making it findable”
