Light or Glimpse for fifth level spells. Blindness/Deafness, Chaos Bolt, Friends, Mage Hand and Command can all be useful as well. It also depends if you have a fighter-type that would benefit from Light more so than… say a wizard.
I personally enjoy the 5th level Magic Missiles spell the most because I’ve found it to give myself and others the edge while fighting certain adversaries on foot or in close quarters with melee weapons. Land’s Stride is usually my go-to 7th level spell when I don’t already know what I’ll need to do and want to get some versatility in there too. Locate Object is another favorite 8th leveled spell of mine because there are so many items, people and places I want to look out for.
