Any tool recommendations for creating UML diagrams/adjacent. For systems/processes?

Sequence, flow, state machine, use case etc.

Whenever I search it’s either vendor locked subscription SaaS or some basic but usable tool that costs $800 for a license, Im happy to pay non-enterprise level amount for a good tool.
(I know there’s a having cake and eating it too argument here)

But wondered what options am I missing?
