aW band selection

Getting the Se 40mm but unsure which band , person is highly sensitive skin , has worn Fitbit charge 4 for years though no issue made of elastomer,simple Watch like strap , Online agent suggested the sport band s/m but I’m reading quite a bit about not easiest to put on and off? I know loop is out as aide said it stretches out easily and with a thin wrist can come off, This is not an inexpensive item so any help be great ,.. and I do know know want a Nike just do it lol would though the material spots loop with the Velcro be easier for putting it on, We are not able to get to a store and try options. Agent had also suggested larger cas 44 mm but we know form reading here that would not be good for a frailer slim wrist 6 inch so opting for 40mm. Thanks so much
