The quality of AAC depends a lot on the encoder. The iPhone does it pretty well, Android not so much.
That’s what the audio nerds say, at least. Personally I can’t really hear a difference except when using the headphones with the microphone, when it reverts to some ancient codec with more noise than signal.
Also, battery life on the 7 series is pretty bad. My old 3a had awesome battery life, but since then Google started making their own SoC. They still use some third-party chips which they don’t control, and it’s affecting power efficiency. I’ve heard rumors that they’re expected to have better control of power consumption around the 9 series.
All that being said, I love my Pixel 7a, but I frequently have to top it off to last me a full day. I can handle that, but if you don’t have access to a charger during the day I’d consider other options.
The first was probably Duke Nukem 3D, released January 29th, 1996:

If you consider their hacky approach to 3D cheating (they didn’t support one part of a level to be above another, and implemented looking up/down by just distorting the image, so all corners were too pointy), then you’d have to wait a few months for Quake.
The first actually 3D first person game was Quake, released June 22nd, 1996, and it let you swim:
