If you have a large country and can hide your airfields hundreds of kilometers from the front, the F-16, Rafale, EuroFigther and the F-35 are all fine, but you have more options with the F-35. If you're a small country, like the Baltics, or Denmark, they are a silly choices if you expect to fight a battle at home. You simply don't have anywhere to service the planes after missiles and drones take out your three airfield equipped for the F-35. In those cases the SAAB Gripen is a much better choice. You can service is straight of a highway with basic tools and conscripts. It's also a plane designed to fight Russia, so if that the enemy you expect, it's fine.
It's not so simple to 'take out' an airfield. Actually it's very tough.
Ironically, S300's from Russia. That's what Ukraine used to deny Russia air superiority. You can fight the orcs with orc weapons but you cannot fight them with American made airplanes because the US can stop support at any time.
More realistically though, I'd imagine many European nations are eying twin-engine multirole fighters like the Rafale and Eurofighter. These have a larger range and payload than the F-35, bigger radars and pylons and the all-important high top-speed (mach-2 intercepts are a must-have bordering Russia). These can be had cheaper than the F-35 and are generally better suited to a high intensity inland conflict.
