Delete your other socials if you want to. I'd say especially any platforms under the Meta umbrella.
I deleted my FB account permanently in 2020 and it was a very good decision. The friends and family who want to keep in touch with me still do. Don't need FB for that. And glad all my devices are free of Zuckerberg spyware.
I turned my X account into an advertisement for Nostr though and I spend a few minutes a day looking for posts from bitcoiners and liberty accounts to reply guy them about Nostr.
