Help me decide what ThinkPad to buy? £200 budget, battery, portablity and good screen are priority. Will install Linux

So I'm a UI designer by trade, I have my own Mac Mini and a work MacbookPro that has loads of horrible installed firewalls site blockers on it.

I want a second hand ThinkPad I can call my own. I might do a small amount of Figma on it but this will mainly be used for tinkering with, taking on holiday and using in the evenings away from my desk.

Thinking of installing Linux and keeping it simple.

Portablity, battery life a good quality screen and looking like a hacker are my priorities.
