Honestly, I never really use it untethered enough to give you a good answer. But I can say that notebookcheck’s battery tests are pretty good, and they test enough laptops to compare well across a large number of models and generations.

I’d say if you get a Ryzen, yeah. I have a P14s gen4 AMD that I use for my primary machine, and game on successfully. But I also have an old T14s gen1 AMD that work let me keep when I got refreshed. Right now I have Windows on it, to play some games that don’t work well in Proton, but it works fine in Linux as well.

If you can swing it, the T14s gen3 with a Ryzen 7 6850u was a truly excellent machine, it’s what I have for work right now. But we won’t see it coming off lease for another couple years, so it’s a bit early for good prices on the used market.

Just grab a 3-4 year old 13" business class laptop, like a Thinkpad X13. When they come off lease at 3-4 years, they hit the used market at pretty great prices. Some are in rough shape, but use trusted sellers who sell at reasonable volume, and their condition grading tends to be pretty reliable.

Be careful about upgradable RAM, or getting at least 16GB. It sounds like you’d be fine with 8GB for now, but 16GB will get you better life out of the machine.

You may want to replace the SSD straight away, depending on the write cycles. I’d probably just grab one with 256GB, and get a replacement straight away. Lenovo has all their hardware maintenance manuals online, to make checking compatibility and performing the upgrade pretty easy.

Hopefully they plan to stabilize what they see as core functionality, and then build out features. Some people won’t consider it ready until this or that feature is added, but many of us who just want a WM+ can start using it once it’s relatively stable.
