Grinder recommendation [$800]

I’ve bought a bambino plus today off of marketplace for an insane price that i simply couldn’t pass up on (could definitely sell for more than i paid for if i dont end up liking it) upgrading from my delonghi ecp 3420, but now im putting most of my budget for a good grinder and buy accessories for the bambino if you could also give recommendations for a bottomless portafilter and basket 18g and 20g, wdt, tamper and anything else i should need. Anyways back to topic of grinder what should i get at this budget? I dont have any experience with either conical or flat so no preference yet, i mainly use medium or dark roasts, milk drinks mainly flat white and iced latte.

So far i have some idea in mind on what to get but please do share options and opinions!
