Any tips for dealing with resolution scaling on an orthographic camera in Unity?

I'm trying to get my game to work with different resolutions since I've had issues with UI elements and game objects not scaling to different aspect ratios and resolutions in the past.

I currently clamp player positions within the viewport so they can never go off screen and I'm going to be anchoring UI elements and keeping them a fixed pixel width. However, I still have to deal with moving all game objects without limiting the amount of space players have to work with. At higher resolutions, players have more space to move around, but at lower resolutions, players have less room to move around.

Is there any good way to solve this? Or is my best bet just to force a single resolution like how I've been doing before?
