https://www.curseforge.com/minecraft/mc-mods/minihud <- Minihud. Allows you to make a mini F3 mode AND easily access more information like seeing light levels on blocks or Beacon range. Will require configurating
https://www.curseforge.com/minecraft/mc-mods/free-cam <- Be very careful with how you use this one. Use this only to see your builds from a different angle or help spawn proof a farm. Using this to E.G. find caves and mine OR otherwise look for resources will get you banned.

https://www.curseforge.com/minecraft/mc-mods/horse-debug-info <- Horse stats
