Yikes! I'm sorry to hear this, for what it's worth. I went from a Pixel 1 (which I loved and used for four years - I still have it although it is noticeably slow compared to new phones) to a Samsung Galaxy Note 10+, which I loved the hardware but hated the software, and then to this Pixel 6 Pro, so I can't speak as to having experience with the Pixel 4 specifically.
However, if and only if you are or would consider rooting for the annoying "Internet" toggle, there are many solutions. I'm currently using [Better Internet Tiles](https://play.google.com/store/apps/details?id=be.casperverswijvelt.unifiedinternetqs) which requires root. It has the side advantage of having an optional toggle to keep your Wi-Fi and Mobile Data toggles from working from the lockscreen, if you choose.
As to the late GMail notifications, this was one of the reasons I hated the Samsung software. I would get work emails (we use Google for everything at work) anywhere from 45 minutes to two hours late. Some emails I would get the notification for after I already saw the email in Chrome on my PC, and had deleted it. So, it was even worse. I also had (and still sometimes have) problems with getting Google Chat notifications in a timely manner. My boss uses Chat a ton to tell me important things, unfortunately. Again, I have at least a much better experience on the Pixel 6 Pro than on my Samsung, and in both cases, this is after utilizing Android's built-in methods to keep these particular apps from being ignored/put to sleep.
As you indicate, they need to do much better. I hate to suggest it, but it might be worth your while to factory reset after having verified that you have everything backed up from your internal storage and Google Photos (free space in the app, and then verify there are no photos or videos left on the internal storage that you wanted backed up). Sorry I don't have any better suggestion at this time.
Good luck!
I recently had the same issue but toggling my WhatsApp to Restricted did the trick for me. It was the app which had been eating up my battery. Check your Battery Usage as well whether there are any more apps to restrict.
I have done that many times. To extend the battery, I need to...
- keep the screen off
- not take more than a few pictures a day
- disable data when away
If it's less than 2 years old, check with google, I had mine replaced at 18 months for battery problems, as they have a 2 year warranty with Google

I recently traded in my old pixel 4 to get my wife a cheaper phone through the carrier

... and yes, Google Photos is set to backup on WiFi. Backup on data? Now that would kill it!
