Comfortable at full-back, wing and outside centre, Smith also filled in at fly-half late last season under Franco Smith. While that is unlikely to be an international option, the 25-year-old believes his adaptability has strengthened his case for selection.
"I think it's just being adaptable to anything," Smith told the media ahead of Saturday's meeting with Fiji.
"There's so many times where, for Glasgow for example, I've been called upon when other people have been injured for a time. I've slotted in at 15 and then had to play a bit more in the centre at the start of the season when Shuggy and Nonz were coming back from the Lions. Then playing on the wing when the Kyles [Steyn and Rowe] went down and Dobie [injured] his shoulder.
"It's been able to fill in and make it the most of an opportunity so it becomes difficult for the coaches not to pick me because I can cover so many positions."
Asked which position he enjoys most, Smith admitted it has changed throughout the season.
"I think at the start of this season I would have said maybe 13. Then I had a run at fullback and I really enjoyed that. And then towards the end of the season, playing 10 was quite fun just because it was something different.
"I'm not really bothered as long as I'm playing."
After returning from a serious knee injury last year, Smith has been patient for opportunities with Scotland and is eager to make the most of another chance.
"There's obviously a lot of great players in this squad.
"If you look at some of the names in our backline and how they've been performing over the last few years, it is a competitive place in the squad and I think they've been performing so well.
"I've just had to bide my time a little bit, but it's nice to still be recognised and added to the squads and rub shoulders with these guys.
"You learn so much off them, even when you're training against them, and it's competitive through training as well.
"So I'm still definitely learning a lot when I'm in the campaigns, but I'm just excited to play whenever I can get a chance to play."
Four years on from his Scotland debut against Argentina, Smith is preparing to win just his 13th cap and says every appearance remains special.
"I've not played too many games for Scotland so any time I do I really cherish it, even with the breaks between. I'm just excited and it makes it even better that we'll be at Murrayfield as well."
Scotland face Fiji this weekend, despite the visitors arriving after a heavy defeat to England. Smith insists they remain a major threat, recalling last summer's defeat in Suva.
"We see that as a bit of an outlier. They're obviously a very dangerous team. You saw what they did to us last summer when we played them over there. They put us to the sword.
"They're a top-class team and they've done so well over the past few years. They've had some close results against some big teams. They nearly got themselves to a World Cup semi-final in 2023. They're not to be taken lightly."
Fiji's offloading game will pose a unique challenge, but Smith says Scotland must stay disciplined while sticking to their own strengths.
"We're not going to be delusional in the sense that we're going to snuff everything out and they're not going to get an offload or a line break.
"It's how we respond off the back of that - hustling back in defence if they get the better of us in certain areas.
"Also on the other side of the ball, sticking to our game plan and knowing where we can get the edge on Fiji and play our more style of rugby against them that plays in our favour.
"It's finding that balance of not getting caught in a game that's loose and maybe forcing things at times because that could play into their hands."
With around 50,000 expected at Murrayfield, Smith hopes the conditions produce an entertaining contest.
"I think hopefully the conditions stay like they are today - warm and dry. It would suit both of us. I think we'll definitely enjoy it with a good crowd and some good weather and a dry ball hopefully."
