My personal laptop is a Dell 7490 running Ubuntu. It's from around 2019 and the cpu is the i7-8650. The ram and nvme card are replaceable so it currently has 64G and 2TB respectively. In this configuration it's very pleasant to use and I see no compelling reason to move to a newer machine. Parts or entire replacements are cheap. I think if you want to run Windows it might be more painful as the upgrade treadmill might force you to a place where drivers are no longer available. Battery life is poor compared to a Mac but about average for a PC (I've replaced the battery once so far though).
