Oh, I just want to pitch this in to just give you options/suggestions to consider (though its up to you on what you want to do).
While yes, dynamic mics reject alot of background noise, you may also want to consider shotgun mics such as the Audio Technica AT4053B, AT8035,or the Sennheiser MKE600. I currently use an MKH416 (and its wonderful for even voice acting and I'm surprised its even an industry standard in BOOTHS.. freaking booths, where voice overs for voice acting and other things aside from singing are done... and that's just its second purpose since its mainly used in sets where there are actors and what not... though I cannot say the same for other shotgun mics) and its wonderful, though its expensive and I only got mine during a sale. With a shotgun mic, since they're mostly, if not entirely, Condensers (but with the intent that they are very, very directional with pickup pattern), you may not need a cloudlifter in your system, and the shotgun mics I recommended are cheaper than the SM7B. However, if you like to move alot while you speak (even some streamers are guilty of this sometimes), shotgun mics are not ideal at all (which is why some studios even have other mics in-hand because some voice actors like to get "physical" which means they like to act physically while doing the voice acting to help with emotion and/or intensity).
That said, I also have a bias in favor of the SM7B. Its a lovable mic, especially in post, and is actually quite good for singing. Yes, MJ used it for an album, but its not suitable for everyone else's voices, though it can do it very well. Its just that Condensers are much more ideal for singing (shotguns don't count, IMO, due to how they've mostly been designed for). But for podcasts, voice overs, streaming, etc... where its a live environment or in a poorly treated room (not everyone can treat their room, even if they have the money, mostly because of other factors), Dynamic mics are ideal for that.
There are also weird exceptions that may also be in your favor. Some people even use shotgun mics for podcasts due to them wanting a more natural and more conversationally-sounding, well, sound in their podcasts, rather than having a "voice of god" effect. There are also end-address Condenser mics like the Rode Broadcaster (not to be confused with the Rode Podcaster or the Procaster, as those are both Dynamics) which is surprisingly very good at rejecting background noise, though may not be as good as Dynamic mics. Some even get the DBX 286 S and plug that to their interface's line-in and let it do the heavy lifting and with the benefits of a compressor, de-esser, EQ, and even expander/gate (which helps so much in reducing background noise) along with their SM7B, RE20, some even like using it with their Condensers, I have a friend who uses this with his MKH416.
Anyways, I'm just suggesting things that could help you out. I also do recommend the AG03 like the others said since its great value as an interface in general.
