That depends on the tRPG you're looking to join.Agreed, Roll20's Find a Game service is still one of the best ways to find games online. I've used it many times. Mostly for one shots. Either just because I wanted to be a player for once or because I wanted to try a system I've never played, usually both.
It's pretty bad for RPGs that mostly exist on other VTTs; which should be somewhat obvious as it'd be kind of weird to post an ad on roll20 for a game you're running on a competitor.
For Pathfinder folks, Discord is the key to finding groups. There are two big Pathfinder 2E discords (one is both 1E and 2E, the other just 2E) and both have active subchannels for free games, one also has a subchannel for paid games.
I suspect Warhammer and Savage Worlds people have something similar going on, since their games are officially on Foundry.
It looks like DnD games will soon mostly be inside the DnDBeyond ecosystem with that new Sigil VTT, but time will tell. I understand it's free at present and mostly or wholly not-monetized. Folks expect that to change, but they were very smart going free for now. If it does monetize later - how well they handle that will determine where people land.
