I have used Linux on multiple Dell Latitude laptops (6510, 6540, 7380) and it has always worked out of the box and completely flawlessly, including all integrated peripherals (even WWAN cards, smart card reader and dual GPU setups), EXCEPT for the fingerprint reader. Sleep and Hibernate both work fine, external monitors just work, docking station with its peripherals just works, ...
The missing fingerprint reader is no big deal for me since I didn't plan on using that anyway.
tl;dr: I can vouch for (at least these) older Latitude models being very fun to use with Linux. I'm using Manjaro exclusively though, other Linux (or BSD) variants may or may not work as well....
