hi and welcome. to give advice is not easy since there are so many options

are you more of a tootlepuffer (I am one), that likes mouth-to-lung hits instead of direct lung hits?
or do you want a lot of vapor and direct lung hits? how about flavor, is that important?
do you like a tight draw or more open draw?
and we havent even talked about the thousands of different juices that are available.
I startet with an Evod 2 which helped me get away from the stinkies. After that I went on a journey and tried different tanks and mods but until recently I stuck to these 2: The GS Air with 1.5 ohm coils and the Nautilus Mini, both on an Istick or a Coolfire IV Box Mod. But again, this is for tootlepuffing. For cloud chasing/sub ohming (which is not something I do a lot) I have a Subtank Mini which I use on the Coolfire IV, an Aspire CF Subohm or a Zero Modz Box.
The coolfire I can highly recommend as it is inexpensive and covers a beginners need (imho) for whatever tank you want to try (as long as you don't want to go below 0.5 ohm and/or try Temperature Control Vaping)
the best idea is to find a B&M close to where you live and then try a few things out. I did a lot of trial and error first until now, after almost a year, I got the setup that is just perfect for me.
