Edgerunner

"Even though he hadn't yet sworn an Ideal, Edgerunner glowed with Stormlight (would it still be Stormlight for a Knight Awkward?). Power rippling through him, he spoke:

Books before friends.

17th Shard before the real world.

Release dates before birthdays.

His faint glow sparked into a bonfire of Light."

Do I have to swear an Ideal and join an Order now, or can I do that later?

In answer to your original question, as noted most of the magic systems are portable, but in some cases the effort you need to make to port them might be difficult.  For instance we know it is difficult to take a Spren off of Roshar, and we know that some other worlds don't have the freely available investiture that Roshar has in Stormlight, so surgebinding off world would be complicated.  there is nothing preventing it, but you may have to bring your own fuel.  The Metallic arts from Mistborn, on the other hand are fully portable.  You don't even have to bring your own metals, you can use metal from the world you end up on, as long as you are sure of its purity.

BioChromatic Breath can be taken elsewhere - as proved in Oathbringer - but if you run out and can't reclaim it, you'd have to go back to Nalthis to get more. Metals on other planets might not be Allomantically pure initially, but any metallurgist could get it right for you. Scadrian magics would definitely be the best for Worldhoppers. The problem with taking Stormlight off-world is that it leaks. Even if it is infusing a perfect sphere, you have the same problem as with Breath, in that what you take with you is what you get. Assuming your gemstones manage to keep their Stormlight through the entire trip to another Shardworld. Aons are useless in Teod, a mere ocean away. The only benefit of being an off-world Elantrian would be the perpetual healing - assuming that works on a planet that almost certainly doesn't have the Dor infusing the Cognitive Realm. Given the parasitic nature of the Aviar, they can probably use their powers on other planets; however, this isn't a human ability. Sand Mastery relies fully on Taldain's sun recharging the sand's power. Therefore, the limit would be how much sand you bring with you. We don't enough about Yolish Lightweaving, but judging by everybody's favorite King's Wit, it appears to work elsewhere. Threnodite Investiture has made no appearance and may not be accessable.

Essentially, Yolish Lightweaving and the Scadrian Metallic Arts are the only useful powers off-world in the long run.
