Welcome back after a long break!

Bitcoin Cash (BCH) and Bitcoin SV (BSV) are indeed the most notable forks of Bitcoin. There have been other forks, but their relevance and value are considerably lower. (like Bitcoin Gold or Bitcoin Diamond to mention some of em.)

Your proposed workflow is a good starting point.
Be sure to downlaod the wallets from the official sources, there are few scams out there. Verify the signatures while doing that.

Regarding ur question about non-KYC exchanges:
There are a few exchanges where you can trade without extensive KYC processes but most of them are limited when it comes to higher amounts. You can check them for example right here

Another workaround would be the use of decentralized exchanges (called DEXs): Some platforms create wrapped versions of non-Ethereum tokens, including Bitcoin Cash, that can be traded on DEXs afterwards.
On this way you have to take a few more steps to swap them back to BTC (while using cross-chain DEXs and/or bridges) but you wouldn't face a KYC process.
