Should I switch to a plugin?

I have been working on a magic datapack for about a year. So far, it includes spells, mana custom items, a boss, dungeon generation, etc. I could easily see myself completing the datapack but I do have an important question before I invest more time.

Should I instead make this a plugin?

The scope of my project is decently sized, so it is quite large for a datapack, not mentioning performance (atm it increases the average server tps from about 5 ms to around 14-20 ms). If I want to add even more features like complex combat and AI for bosses and such, based on my research, plugins seem like a good idea. I do NOT want to make this a mod since I want it to be easily accessible for people to play with themselves and others.

If I do decide to make it a plugin, should I finish my datapack then make it into a plugin, or just "finish" my datapack in an incomplete state with only core features, so I can spend more time learning how to and making it into a plugin?
