Check out refurbished Thinkpads T480 (14in) in your area. I basically got one that basically ticks all your boxes. Additionally mine has 32GB RAM, 500GB NVME SSD and a free slot for another small formfactor NVME card. It has one internal and one removable battery, so you could get an additional one to switch on the fly.
The T480 was the last Thinkpad model with “real” upgradability and was a popular business choice. Companies unload them in bulk. When I was looking for them the availability was good.
