Not OP, but yes. For personal use, you don't have enough traffic to establish reputation, so you get constantly blocked regardless of DKIM/DMARC/SPF/rDNS. Receiving mail is reliable though, so you can do that yourself and outsource just sending to things like Amazon SES or SMTP relays.

Been selfhosting personal low traffic email since the 1990's, I don't have that problem.
This is not a job for the big guys. You want someone local who will take care of you. They also come when a computer fails, ensuring updates are applied to them. Not by come I mean physically sending a human to you. This will cost some money but you should be running your business not trying to learn computers.
OK that's your opinion, in my view a business should selfhost if they want to maintain data sovereignty.
> everyone else should pay their local small business self hosting company to host for them.
That assumes all small business have at least one "local small business self hosting company" to choose from.
