After jacking up thousands of vehicles for installing tires, all I can say is sometimes you have to get creative. I have lifted many vehicles using a something other than the "official" jack points. It might be a sturdy part of the frame, or even an A-arm. There are many ways to do it, and so many other issues, like air suspension, etc. It's crazy anymore without obvious jack points like some cars have. I have seen some older Toyota's for example, with jack points that you could get the whole car in the air with 3 floor jacks.
2 floor jacks are a minimum for most car maintenance. And, usually no dedicated pinch weld adaptors. I just use a wood pad on my floor jack saddles for most stuff, or a hockey puck as needed, which do not need a groove either. Just the weight of the car will make it's own groove.
