You could look at some more used ThinkPad options like a T470 or a T480. They can often be found for cheap refurbished on eBay. I would also take a look at online benchmarks to see what fits your requirements. In my experience, that works better than looking at spec sheets.

A T480 is about 500 euros, just as much as a T14, but with a worse CPU.
