You mentioned receiving 10s of spam per day - are they being classified correctly and put in your spam folder or are you seeing them in your inboxes?
My mx hosted with hetzner also runs rspamd. Of the 32k mails received in the last month, 40% were rejected (postfix DISCARD, so the sender sees the mail as accepted but its sent to /dev/null - this only happens to mails scored very highly as spam, or sent to a spam trap address), 10% were greylisted and 1% were delivered to the spam folder.
So I'm also receiving 10s of spam per day, but they're all delivered to my spam folder with rare errors.
With the exception of an issue delivering to AT&T recently, I haven't had any outbound deliverability problems in a few years, but then again I don't send very much mail at all - perhaps I'd have more trouble if I did but most of my mail is incoming.
