Bitcoin cash - can someone ELI5 the best way to buy and hold? Few questions.

Hi all,

I am interested in buying some Bitcoin Cash, but I can't find the best method to do so and hold long-term. It appears that traditional Bitcoin hard wallets like Trezor and Jade don't work, and I can't seem to find one that do. I have a few naive questions and any help would be appreciated.

What exchanges should I buy from?

Any non-KYC exchanges?

What wallets can I use that will work with Bitcoin Cash?

Are the transactions to/from these exchanges to wallets the same as a bitcoin wallet?

Can I buy portions of bitcoin cash similar to SATs or is it just the "whole" current amount?

Again, thanks for any input as I am trying to wrap my head around this.
