Can’t decide on a class

[Keravath]

If you don't mind a reduced emphasis on magic then a ranger/rogue multiclass can be very good at exploration and combat.

You could take 5 levels in ranger - either revised ranger or gloomstalker - and then switch to scout rogue which would add expertise in survival, nature on top of the rogues usual expertise ... which could be stealth and perception to start.

Depending on what level your group is at now, you can start a fair way along the way.

Focus on using a bow, archery fighting style, possibly take sharpshooter if only for the style points - shooting at long range and ignoring 1/2 and 3/4 cover. The -5/+10 benefit can also be good.

Gloomstalker picks up darkvision at 3rd level so you could start variant human with a feat (like resilient con or possibly observant depending on how your group handles perception/investigation checks and passive perception.

------------

Other options could be ...
- melee hexblade blade pact warlock with GWM/PAM - this has some spellcasting and is very good in melee (variant human, PAM to start, pick up resilient con and GWM later, use darkness and later shadow of moil to get advantage on your attacks)
- arcane trickster rogue/warlock multiclass
- some sort of paladin or paladin multiclass
- arcana cleric could be fun - spirit guardians + booming blade in melee
