For non-KYC, P2P, go with https://bisq.network.

I've done 100s of trades, can fully recommend it.

It may seem a little daunting at first as the UI does little to hide its immense features (they're working on a UI overhaul), but take a stab at it, it's really great.

You have a couple options. The desktop app throws you into the actual network, and it's a full-fledged and featured application. For transacting though, it assumes you already have some Bitcoin to use for deposits.

If you don't have any, the Bisq Matrix Space has a chatroom for first-time buyers. It's all P2P.
