As others have said, it’s largely up to you. We are volunteers in this citizen science enterprise and we have some latitude.
If I felt so inclined I could go to a local park at certain times of the year and record 50 individual Canada Geese. It would eventually bore me and is not likely to help anyone else (unless you’re a researcher who really wants lots of Canada Geese, in which case ping me). I would rather sample many different birds, plants, and maybe the odd groundhog. Of course, it might be different if I saw several individuals of a locally-rare species; I’d probably want to record them all.
One thing I do to illustrate the number of a species is to take one or more close-ups of an individual and then wider photos of their group, like this: https://www.inaturalist.org/observations/48018100
In part it depends on your interests. I’m a generalist, but if you’re really interested in a species or genus you might want to be more detailed in your recording.
Another thing that enhances my experience is Projects. There are many kinds, but I recommend you start with a local place-based one, like a National Park, one or more taxa, and maybe something for fun. Participate in a BioBlitz. You may also find some of your Observations automatically added to Projects of a more serious nature, such as this one for Wildflowers. Seeing what others are observing helps me decide what to photograph, and how many.
By the way, my joining a few Lichen projects reflects my ignorance, not my expertise. This is a learning opportunity.
Also, while you’re still new here, fill in whatever you can in the Annotations fields. For animals (including birds and insects) that usually Alive/Dead, Life Stage, and Sex. For plants it’s Flowering, Fruiting, Budding, etc. You won’t know all, but do what you know to make your Observations as detailed as possible.
And, yes, have fun. Revisiting past nature walks by uploading photos has helped keep me busy and sane during the pandemic.
