My two cents
Here a few of the tools I've used to create wireframes that I like:
Pen and paper: really good when you just need to quickly share an idea during a workshop
Pop by Marvel: great to turn a wireframe made on paper into something clickable
Keynotopia: great when you want to create wireframes together with people that don't know design tools but know powerpoint, google slides or apple keynote.
Miro: miro has a great wireframing toolkit and it even can allow you to create interactive prototypes.
Wireframing kits: I've also used in the past wireframing kits for tools like Sketch or Figma, just google "Wireframing kit" and you'll find plenty. I've used Platforma which is available for Figma, Sketch, Adobe XD and even Bootstrap. If you want more, here my personal bookmarks with more wireframing kits
These days I really like to use Miro as it's pretty fast and allows also to work with sticky notes to gather ideas, make votes, etc. And once the team I'm working with is used to Miro I find it great to stay in the same tool when it comes to wireframing.
