I find rabbit care to be very similar to guinea pig care. They eat relatively the same things, they need daily vegetables, limited pellets, unlimited hay. They need as large of a space as you can possibly give them, with a cage tall enough that they can stand up completely on their hind legs without touching the top. They should have a second level in their cage (it doesn't have to be a complete level, just as long as they can reasonably hop up onto it). They should have as much time out of the cage as possible, again with as much room as you can safely rabbit proof.
Rabbits are way more destructive than guinea pigs (at least, in my experience) anything left within reach should be expected to be chewed on. Even if it happens to be on your person at the time. Mine have destroyed laptop chargers, my favourite sweaters, wired controllers for my gaming systems, cords for my headphones, clothes I've been wearing, everything in their cage. It's very easy to fall back on 'oh, it's not too close to the cage, they can't get it!' (they totally can).
Litter training does really help with rabbits, but at the same time it does take some upkeep. There are rabbits that will use their box almost 100% of the time, and then there are ones that will occasionally decide that it's too much effort to wander all the way over there to do their business. Make sure to try and keep their hay located in or around the litter box, anywhere with hay in my cage tends to eventually become a prime location for poop. They are usually really good with using their box, but if I forget to thoroughly check all of the hidden little corners, they can start up a new litter box on their floor that can be a pain to stop them from using. I'm not sure if this is actually a thing, but I recently changed their litter box to a slightly different cat litter box and for weeks they would not use it. At all. I had to toss the new one and go out and buy the exact same model as my old one before they would go back to using it (they were the same size and general shape and everything! the new one was just like five dollars cheaper).
You will need to get a lot of things for them to chew. I really, really do not find buying them the little grass/wood/wicker toys worth it. I'll get them on occasion as just special treats, but for the most part I will just toss large cardboard boxes or tubes into their cage, maybe several sheets of newspaper, safe wood sticks, some horse hay cubes. They're equally entertaining in their eyes, while being way more worth it to invest in. They will shred that fancy pet shop toy in a matter of hours. I also buy hard plastic baby/dog toys for them to toss around.
Lastly, your rabbit will need vaccines against myxomatosis and RHD
Depending on your location, this may or may not be true. My rabbits have never needed any vaccinations, just general yearly checkups.
