Your list of CEX with p2p and Bech 32 segwit address is okay but I think you shouldn't have included binance since they have delisted Naira p2p on their platform but that notwithstanding, I like the disclaimer that you attached to your post because no matter how reliable and reputable a CEX may be, it can still be prone to hacks and manipulation, apart from performing p2p transactions, these CEXs is not really important since they don't offer full security of your assets. Anyways, it will help people in the local board especially newbies to know the CEX platform they can use to perform p2p transactions since there are many CEX that are fake at least I haven't heard any complaints from anyone about these CEXs you have listed.
       For someone who is holding Bitcoins for long term, these CEXs should not be used to store your coins. You can use a self-custody wallet like electrum since it is safer to store your coins and also has a Bech 32 segwit address.
