Some base level of cardio only makes it harder to gain muscle mass if you are really short on time. I don't think it'll hinder the average person to maintain a surplus – first, you don't burn that many calories exercising as you might think, especially once you're adapted to it, and second, our food environment makes it relatively easy to increase calories if needed.

I'd also challenge the idea that cardio interferes with your recovery for weight training purposes.
