EOS Rebel T8i Settings for wrestling

I'm renting an 18-135mm IS USM lens for my Canon T8i and was wondering what the best settings would be to get great photos of wrestling this weekend. I haven't had much luck figuring out the best ones for other lens as some gyms having different lighting at different areas or I have to improvise and use a larger lens and then forget to change my settings again so all my pictures are too dark to edit without them pixelating. It's very limited time to figure it all out before the sessions begin each time before I just have to go with what I have it set at. Any help is appreciated for low light and plenty of light as I don't know what the lighting will be like this weekend.

Actually, lighting does change. Some mats have more lighting than others. Some are partially under railings causing shadows, etc. I just never know. This weekend they just announced that there will be 14 mats going for 2 days. I'll be all over the place up and down trying to get my shots. It also depends on where I can get in. Some have room for me to walk down the middle and others I have to bob and weave around the outside and lean over people.

Moving away isn't always an option. There is a lot of people around and other mats going to watch out for too. Lighting does change between mats. They are never the same and sometimes I take pictures between 3 or so mats at the same time turning my to each one. I can't check exposure for each one in-between shots.
