Good luck running your own mail server these days, and getting your messages actually delivered to Gmail and Outlook/O365 mailboxes. It’s possible, but a hassle, and the rug can get pulled at any moment.
Just configure your SPF record properly and you should be fine having emails delivered to gmail. I work in tech support for a small software company and every single time a customer is having issues with our email server not delivering to GMail, it’s due to their SPF record being borked (which is on the customer’s IT department, not us)
