From personal experience (I don't use SD cards often) I would rather have another USB A or C port instead of SD port. USB SD card readers are so much cheaper and smaller than Framework expansion cards, that having one in a bag takes less space, and you can carry them like USB flash drive.

Well, that's one of the Framework's value props: you can have both, and swap out the card reader module for a port module if you want to. And if you aren't sure, you can always carry the module with you, which is no worse than if you had to carry an external reader.
