What is a good martial art for me to learn? I'm 5'6 140 lbs. male. Just would like educated opinions lol.?

I'm 22 years old never had any sort of training. Looking for something to get in good shape and also have a good self defense. Any suggestions? Feel as if my arms would be too short for boxing and legs too short for kickboxing lol but thats just my personal opinion. If yal have any advice let me know. Thnx.
