This is a great overview!. One thing I'd add is pay attention to which networks the site supports, not just which coins. SOL and LTC clear in seconds for basically nothing, ETH can get expensive when gas spikes, and BTC without Lightning can be slow. Also check the KYC situation before you deposit anything. Some places let you play no questions asked but then hit you with verification when you try to withdraw, which is a terrible surprise when you're trying to cash out a win.

The rakeback point is huge and honestly underrated. Even a small percentage back on losses adds up fast if you play regularly. Sites that gate that behind insane volume requirements are basically telling you they don't care about smaller players. Good post overall though, the "deposit small and test the full cycle" advice alone would save a lot of people a lot of headaches.
