This is perhaps only peripherally related...
Janice likes to sing with a near finished mix. She sorta riffs off of the rhythm instruments, fills and solos. Meaning her phrasing often is significantly affected by what else is happening in the mix.
We use Nectar 2 for vocal processing...mostly, as folks have mentioned, compression, eq and reverb with the occasional delay added. Nectar has wonderful presets, i.e., you select your vocal style and let it do its thing. Often no or only minimal tweaking is necessary for the preset.
As others have mentioned a solid DAW and a few plug-ins can take you a long way. Of course you will eventually reach the point where like cow bell you can't have too much in the way of plug-ins.

Have fun on the journey.
