The app does not change between these pages. What changes is what a project means, which pillar carries the weight, and which part of the week is the one that keeps breaking. Pick the one that sounds like yours.

Running a household

More than one person, one list, and a streak each.

Working for yourself

Client work and your own growth, competing for the same week.

Working for someone else

The commitments a team tracker never holds for you.

Studying

A plan that survives contact with a bad fortnight.

Practising something

Hours logged against the thing you are trying to get good at.

When the usual systems do not fit

Built for weeks that are not rectangles.

Changing direction

Work nobody is chasing you to finish.

Questions

Picking one, answered.

No. It is one app with the same seven record types on every plan. The pages differ because the same feature means something different depending on who is using it: a project is a client deliverable to a freelancer, a block of the syllabus to a medical student, and a house move to a family.
Most people are more than one of them, and a few are none. The pages are a way in, not a configuration step. Nothing you pick here changes what you get, and there is no template to choose during sign-up.
The free plan covers 2 active goals, 5 active projects, 20 open tasks, 5 habits and 5 skills, and the limits count only open items, so finishing something frees the slot. Sharing a space with other people is the one thing that needs Pro, which matters for the household pages and not much for the rest.
Families, couples and working parents mostly do, and study groups and small teams sometimes. Everything else works in your own space. One Pro subscription covers 5 people in a workspace, and the people you invite are never asked for a card.

You are probably three of these.
It is one account.
