Perhaps https://puri.sm/products/librem-14 should fit well for your requirements. I'm happy with their previous model, Librem 15.
- Repairability/longevity
- Privacy and security
- Usability
Purism explicitly prioritize security (https://puri.sm/security) and privacy (https://puri.sm/posts/tag/privacy/), unlike Framework. Intel ME is disabled (for Librem 15, also neutralized), hardware kill switches are really convenient. First class Qubes support, it can even be preinstalled (it's what I use).
Most important things are repairable/replaceable: battery, WiFi card, RAM, SSD, screen (I think). I heard keyboard is hard to replace though, but I had no problems with it. The keyboard is great, but the touchpad is worse than the one in Macs. I use a mouse. The laptop is thin, beautiful and powerful for my tasks.
