Easy answer is Toastmasters. It helped me a LOT, especially with interviewing.

Look at what local clubs, i prefer in person although a lot are doing zoom based.

Attend different groups to see which one you work best with.

A large group is great for networking, but you might have trouble getting enough opportunity to speak.

Small groups are great for having opportunity to speak, but lacking bodies strains their ability to provide oversight.
