The most typical litter box is probably a normal box (similar to a cat’s) where people put litter to line the bottom and hay on top of it. This is because bunnies love to pee and poop while eating.
Some bunnies love digging or eating the litter, so it’s become popular to put grates in/on litter boxes which can either be bought or DIY-ed using mesh. This prevents the bunny from eating or flinging the litter out and also prevents them from sitting in pee since lots of bunnies love hanging out in their boxes.
The napkin depends on whether your bunny is a chewer. I don’t think it’s very likely for them to “accidentally” eat something – more often than not the cases of bunnies ingesting napkins or plastics is because they chose to eat it (not by accident). Although domestic bunnies have lost the ability to recognise which foods are safe, they retain their excellent senses and if it’s something they don’t like, they have the capability of going around it – you would notice this when you see how a bunny digs for and chooses that ONE particular strand of hay among so many others just because it’s their favourite strand!
To answer your question, I recommend getting a box with a grate. Non-clumping wood pellets are my favourite type of litter as it’s excellent at odour control and also very absorbent. You can line the box with wood pellets below the grate and put some hay on top of it. Bunnies usually have a favourite corner to pee in so choose the side or corner of the box that is least used for peeing and put the hay there.
For reference, Kurotta’s litter box setup looks like this: https://www.instagram.com/p/BhRb5B4AkYz/?taken-by=kurottabun
He loves to pee in the left corner so the hay is on the right
