Yes absolutely. It gives you a sense of ownership and nobody can shut you down.

You’re also more flexible as in you can email providers very easily by simply pointing your domain DNS to a new one. With an @gmail for example, you’re stuck with Gmail. If I’m @example.com and want to swap to Tutanota from Protonmail, I can just change my DNS settings to the new provider and people can still email the same domain.

It also lets you stand out and I think it makes me look more professional on resumes. If your provider is properly set up, then the spam issue is non-existent, so I also highly recommend not to self host your own email.

You need to be careful and pick a reputable TLD though. For example, .top domains are free which also means a ton of scammers and bad folk use it, so it easily gets flagged for spam. I pay $15/yr for my .dev TLD which is ran by Google so it’s reputable. Also they have a special requirement for .dev domains which require to be https and blocks http on the domain level, which I find to be a security advantage and absolutely agree with.
