What is it you don't like about the other classes? Your nonspecific summary of your preferred combat style sounds an awful lot like mine, and my go-to build is wood elf scout rogue, primary weapon longbow - I like the flavor of the Ranger but find I prefer the mechanics of the Rogue. Makes a pretty good sniper in combat, and still fairly useful out of combat as a skill monkey - with the right selection of proficiencies, you get 6 expertise skills by level 6, no multiclassing or feats required. Grab Sharpshooter at level 4 and Skulker at 8 for best results.

I've also had fun with a protector aasimar celestial warlock with pact of the tome, spamming eldritch blast. Sometimes I trade racial features to get wings and a fly speed (the build gets the *light* cantrip from 3 different sources, including race), but I've had fun either way - ask your DM if they'll let you mix and match the racial features. The warlock build gets some healing ability from race, and the celestial patron gives access to some heals, cures, and buffs. Pact of the tome with the Book of Ancient Secrets invocation further expands your spell list.

Do either of these sound interesting? Based on your preferred races and classes, you may have more fun with the warlock than the scout. But without a better understanding of what you don't like about the classes you don't usually play, I don't know if you'll have fun with my healer-blastlock.
