Welcome to the forum.
There is sure to be plenty of information, and sugestions for you to sort through. Some based on personal preference, and some based on any general information about yourself you care to share.
One very helpful tool in making the decision would be actually trying examples of guns you have an interest in. I don't know If they are available in your area, but many gun shop/ranges rent guns. The cost: is well worth it once you narrow your choices some. If no rentals are available, maybe you have friends with guns you can try.
Some information that might be helpful n getting good suggestions are.
1. Your experience with firearms.
2. Your size, or stature.
3. Your ability to handoe recoil from a firearm.
4. If you have any preference as to brand of firearm.
5. Your budget for the purpose.
