It depends on what size you currently have. If you have the series 4-44mm, you could go for an 11-42mm, which is smaller and weighs less. But basically all the latest models are technically bigger than their older variants, so you’d have to change your size class. If you’re currently at 44mm, the latest size class for that would be 46mm. If you have a 40mm Watch 4, that’s already as small as it gets really - although the latest models do have a way of feeling better on the wrist.

The move goals are just that, trying to remind you to keep moving for your daily health awareness. If it feels foreign then you likely don’t need the watch for health reasons. Many folks that get an Apple Watch are trying to take advantage of the health features and make it part of their life; counting steps, burning calories, watching their heart rates (especially if you have a condition), measuring their exercise progress, etc. The move goals are the most basic of functions on the watch and the most common metric users keep an eye on throughout the day.

I would say either go all in or get a standard watch if you’re simply looking to tell time and/or add some aesthetic.
