Jotform runs a whole suite of connected tools - I've also reviewed Jotform Apps.

And their form builder is nice. The free plan is good for small projects, although it does annoy me they push their AI to build it for you.

My main qualm is their price. $39 per month is rather expensive for just 1,000 monthly form submissions, when there are other builders with unlimited responses.

They do get a boost for being interconnected to a useful tool ecosystem though. You can do and build a lot without ever needing to leave their umbrella.
