There are a lot of generalisations about breeds. Some based in fact, some not. True, some breeds have a face structure that leaves them prone to eye or dental issues. There’s probably a health issue associated with just about every breed though. It’s good to choose based on personality and that is not always apparent with baby rabbits.
If you haven’t gotten a rabbit yet, you’re in a good position to plan for it’s future now. Unlike me, my 1st rabbit was a spontaneous pet store purchase! So you can look into getting a rabbit-experience vet and pet insurance or setting up savings to cover vet fees for any problems that may crop up. As you said, you have to expect health issues with any animal really. No way around it but you can prepare to manage them if they do arise.
Another factor to consider is the time you have for their care. Some breeds require more grooming then others. With lionheads you will likely need to brush and trim their longer areas of fur more often. If your in a position to do that, then no worries!
I ditto the others advice to visit a rescue too. You can see buns as adults and get more idea about the differences – personality and physical. Most in a Rescue will be either mix breeds or not up to breed standards for showing so you could even find some that resemble the look you favour but are larger or smaller and may not have the problem traits that the pure breed may have. One might even steal your heart.
Same with a breeder if you choose to go that route. Visit a few times beforehand. Just observe the rabbits before taking one home.
