You absolutely should own your own domain and use it to email somewhere besides Google. I use Fastmail but ProtonMail is great, tutanota, mailfence, etc. Getting locked out of your email is no joke you don’t want to be in that situation.
I have a paid account with Fastmail and a free account with protonmail just in case something goes wrong with Fastmail I can transition my free protonmail account to paid and use it with very minimal downtime
