You can always get the battery swapped for a new one on your 13 Pro should it ever not get you through the day.
I have a 16 Pro so upgrading is probably kind of pointless.
I will say that the base model 17 looks pretty decent once prices at online shops come down a little. Finally you get the 120 Hz display.
I like the slimness/weight of the Air. The only thing really missing for me is the ultra-wide lens (also for macro photos), battery life would probably work out for me and other compromises are minor.
The 17 Pro isn't a huge upgrade year-on-year, but they finally completed the transition to all 48 MP rear sensors, finally got a decent cooling solution and increased battery capacity (and 12 GB RAM). It finally feels pretty much complete instead of Apple purposefully holding back features. Bit of a bummer that we get the SIM tray version in Europe though, I've been using eSIM for years so the larger battery capacity - while I don't need it in most cases - would've been appreciated.
I'm kind of holding out for a foldable iPhone anyway.
But back to you: what are you missing from your 13 Pro?
