It is not worth it if you need to send marketing campaigns in hundreds of mails per day or transactional email in hundreds that really needs to be delivered to corporate email boxes of "joe@megacorp.com".
For my personal e-mail most of the time I am just on receiving end. For receiving e-mail I don't see much problem. For receiving email only you don't need to setup any of the DKIM/SPF/DMARC stuff.
Occasionally I send some e-mail out but you are not going to be marked as spammer if you sent 1 e-mail a week from your IP address. Most likely it will be delivered and accepted by whatever provider receiving person is using, might be marked as spam - but well you probably can call up that person and ask them to check spam folder.
For spam - don't put your email into every web page that asks you to do it and you should be good. My gmail account that is now ~20 years old started to receive loads of spam only last year when email lists from various leaks started to go around internet. My other email accounts that get loads of spam are on shitty providers that send their own spam.
The realization that my Gmail is nearing 20 years old was not a reminder I was prepared for today. If it's that old, how old I must be now. :-\
I'm similar to your boat, so this is just one more reason I'm going to give it a go, I think. It'll take time to move the stuff I care about off Gmail anyway, so I can sort out the spam stuff as I go. And I'd really like the flexibility of controlling my mail in ways I can't really right now with a hosted provider anyway.
