I agree with Mobuck. A red dot for the purposes you mentioned make the addition of a red dot type of sight the best option. As we age,,, our eyes start failing us. A red dot is easy to use,,, and FUN for many casual shooters. If you have never used a red dot,,, I have one piece of sage advice; "The dot does NOT have to be "centered" within the optic viewer to be accurate. It just has to be on the target where you want the bullet to go." This is, of course after you have zeroed the optic.
I have taught a lot of classes to new shooters & the red dots are well received by most.
And as I have aged,,, my eyes really enjoy them as well.
