Pronouns are what feels comfortable to you.
My preference is they/them for myself. I am not a He/Him, and She/Her feels better than He/Him. However I don’t feel that I look or sound like a She/Her, even though that is who I am inside, and it makes me feel insecure to use them. Therefore I go for They/Them as that feels more ‘right’ to me.
Everyone is different. You just to find what works for you.
