What is the best binding style for 100-page book?

I have a book that is just over 100 pages (seven signatures of four sheets of paper each, so 16 pages per signature, not including endpapers) what would you recommend as the binding style for this book?

My original idea was a split-board binding since I really like that style, but after putting everything together, I realize that it is likely overkill and would probably be extremely difficult since I’m not sure how I could round and back something this short.

I thought about a case binding, but I’m leaning towards trying a sewn-in board binding. Since I never did a sewn-in binding, and have had frustrations/disappointment with case bindings, I figured I’d ask the community for advice.
