A buy it for life workstation, workhorse Windows laptop?

I work in audio post and music production. I do some video game coding as well in my spare time. I currently own a desktop machine that serves me well, but is pretty much the opposite of "mobile".

I'm looking for a Windows based laptop that is fast, reliable and will most likely last me at least a decace without crapping out on me, while continuously providing high performance in DAWs and programs such as Unreal Engine.

I've been eyeing Lenovo Thinkpads heavily (this model in particular, or something similar, as the P14s series with "s" suffix seem to have RAM soldered in, thus unenabling future upgrades), as well as the Asus Zephyrus G14 laptops and Asus ProArt laptops (those two are unfortunately more of a typical consumer-slop grade laptops in terms of the BIFL factor, non-upgradable at all, marketed towards gaming ((the Zephyrus)) or as a direct competitor to a MacBook ((the ProArt)). )

All input is highly appreciated. I'm probably missing a lot of cool options, so I'm open to suggestions. Thanks a lot!
