It's not a Gmail thing:

> The reason why my IP address is visible is because Apple Mail sends emails with SMTP.

Unless you use a proxy, your IP address is visible to an SMTP server, just like it's visible to an HTTP server when you use a web browser. This is not specific to Apple Mail or to Gmail.

Yeah but I think Gmail seems to actually just keep that header rather than nuking it. To be fair I don't entirely know what I would do to fix it since (like the post) this seems like there aren't many good options here.

I think that's common among email providers.

Gmail's SMTP servers are what's adding the received header with your IP address, not Apple Mail.
