I have these 5 in my garden, one or two of them should give you the effects you're looking for. Consider getting two strains for different types of effects.
.
Flo - DJ Short: Unique motivating high. Functional to do tasks at work, not to deal with people at work; social with people.

Kali Mist - Serious Seeds: Up-opiate, floating dreamy high. Social.

Jilly Bean - TGA (Subcool): Extremely up beat and happy buzz great for depression and bad days; High type-Happy, mood enhancing, humorous, energetic; Smells like orange skunk or tang/ Taste so much like Dreamcicles you will not believe it!; Extremely up beat and happy buzz great for depression and bad days. Functional/social depending on amount taken.

Strawberry D-Lite - Sagamartha (I have Elite's Super Strawberry Diesel)
: I did Dutch Passion's Strawberry Cough and probably got a bad pheno - it was weak as if I weren't high at all and had a horrid taste, but it did dissolve anxiety in minutes. A good medicinal strain for anxiety only, but I'd take Serious Bubblegum before Dutch Passion's Strawberry Cough. My Strawberry Cough pheno was an excellent yielder so it was probably a different pheno than Higher Education's which gave him good effects but poor production.
I wanted something with SC's anti anxiety effects but with more potency, and found Elite's Super Strawberry Diesel. He's no longer in business, the next best I've seen (available, as Rez's Strawberry Diesel beans are more scarce than hen's teeth) so far is - Sag's - Stawberry D-Lite. It crosses Strawberry Cough with Diesel, very social but not so functional as Strawberry Cough or Bubblegum because of the potency and Diesel influenced type of head stone. The Strawberry Cough clear high is changed from a Bubblegum like clear headedness to more of a Kali Mist's dreamy chill without as much floatyness.
I've got 3 SSD phenos ranging from a slightly sedative (chill, not couchlock) and forgetfull dreamy state (the pheno with the most noticeable effects) to a euphoric high that is also slighly mind bending. Great for depression, mania and anxiety but probably better for social (hang with friends/go surfing) rather than functional (job/school). Very chill without being couchlock.

"I would prefer a smaller strain"
You can Low Stress Train (LST) so you can grow a 6' sativa in just a foot or two height above your bucket rim. Or start cloning and put in short budcycle clones that finish a foot or two in height.
These three Super Strawberry Diesel are different phenos of the same strain - the first two are a tight bud indica pheno and the third a loose sativa. They have 80+ inches of stem and are 6" and 18" in height above the bucket rim, respectively. The stem is bent around the bucket rim and the branches all become small colas.
