straight sativas will be too "up"
not totally true. sativas can have couchlock too. my favorite strain is STILL circa 1985 columbian gold for it's light trippy buzz and floaty feelings it gave, but if you blazed it all day, it'd eventually couchlock you and after a month of waking and baking it, i'd take a week or two vacation from it to get my tolerance back down. kali mist, on the other hand, just TRY sitting down on THAT!
i think, you're probably like me OP, you're not really looking for a "specific" adjective, you just hate being couchlocked.
euphoria is a "happy buzz" and you can get that in any energy level from speedy kali mist and similar C99 down to stonier couchlocking fare like skunk #1 & jillybean with one of my favorites, 8 miles high right down the middle with a perfectly energy neutral buzz that's all playful fun seeking euphoria with a little bit of a warm body glow that isn't as much couchlock as it is mellow.
if there was ONE adjective you're looking for, it's probably
FUNCTIONAL
or
MOTIVATIONAL
after that, do want a trippy buzz that heightens your senses? those are fun until you overdo them, but they also can make you paranoid too with all of the thinking they provoke. so far, the best indoor i've smoked is high quality seed's haze x skunk which is a little less visual & trippy than columbian, but easily more sticky & potent and maybe longer lasting too with only a hint of "lead eye" that never gets in the way of the single minded motivation level
do you want euphoria? KM & C99 offer that in racy & energetic, but clear headed fashion. i haven't tried laughing buddha yet, but that one sounds like it has serious euphoria like jilly bean, but in a much lower couchlock package.
creativity is another fun trait. it isn't really reported on enough, but i think sativa dominant buzzes tend to have more of it, but remember reading long ago that silver pearl was a particularly creative strain, though many descriptions i've read for various strains mention making art & music.
there's a really wide range of effects out there, but it sounds more like anything you're definitely on the sativa side of motivation and don't want any couchlock. i DESPISE it when a buzz slows me down even a little because i started out spoiled on columbian gold and was super pissed wheni scored my 1st couple of indica buds for just $8, but didn't get high off either... then got more pissed that they never went away and getting high never came back.
if you want a really good indoor strain i won't grow (only because of the name), try TGA sucool's jack the ripper which has a great haze buzz, but finishes in 9 weeks. i'd buy it in a heartbeat if it had a non-violent name and if you want trippy, sannies' killing fields has a buzz someone here called "talk to your dog trippy".
hope that helps. glad to see another person going against the indica flow and trying to get high again
