Are floor seats good at an arena concert? If not, where is the best place to sit?

Ok so I know most of you probably don’t care, but Beyonce is doing a tour again. She’s my absolute favorite music artist, so I of course am planning to buy tickets. I want floor seats as close as I can possibly afford, but how far away can I be from the stage on the floor before it gets too hard to see and I need to just get seats further up?
