I think the choice may depend upon several factors.
1) personal or professional
Are you looking to play in a band or is this a hobby/pastime?
If in a band, you need to check what’s needed so as not to train unnecessarily.
2) do you have space to practice? The instruments may be fairly compact, but a saxophone can be too loud to practice with if you live in a building.
3) where do you envision playing the instrument? If you want something very portable, a clarinet might be more practical, as you can carry it everywhere and play it almost anywhere (not so a saxophone).
