I'll continue the subject of better ships than canon Nessian because I have a list.
Nesta and Lucien - the original idea was good, SJM should have stuck to it.
Nesta and Eris - the chemistry, the parallels, the compatibility, the possibility to explore a political marriage trope being transformed into a real and deep love. Chef kiss
Nesta and Azriel - I really like their platonic ship, how he listens to her, doesn't judge her, and it would have been a good type of friends to lovers.
Nesta and Tamlin - I suppose holidays would have been kind of awkward, but on the edge of peak comedy. But they would have healed together and found a way to help the SC. Nesta is easily absorbed by real charity work with a social cause, and Tamlin would have appreciated her more for this. Also, it would have been a more mature and conscious version of enemies to lovers, maybe enemies and lovers.
Nesta and the Cauldron - because why not?
Nesta and Cassian post-divorce era - you know the shows where the main couple divorces because they collected too many problems, and by being separated, they start to go through this emotional chaos and they understand things and they set new rules because they understand they want to be together, but it requires a new set of rules to ensure their happiness. This is how Nessian can get a chance in my eyes.
Nesta and HoW - like the Doctor and TARDIS.
Nesta and Vassa - I can imagine too much wine and daddy issues talk, leading to an accidental hookup. And after that, who knows?
HM to Helion and Nesta; Koschei and Nesta; Bryce and Nesta. I still think these are better than canon Nessian but I don't feel the vibe for them.
