Unfortunately that link doesn’t help much. Currently among the list of “recommended instances” (followed by a claim that it “doesn’t matter” which of these you choose) are a French-speaking instance, a crypto instance, and an anime instance. Hardly welcoming places for your average person, unless you happen to be a French crypto bro looking for porn in which case you are definitely well catered for.
OP might not have all the details worked out but their point is a good one, and it’s an issue on Mastodon as well. It’s all well and good having a one-liner description about each instance but it can be quite a trawl to find the actual important info you need to make a decision.
