Trump is an authoritarian wannabe. He's too inept at it to be an actual fascist. Sure, you'll see some authoritarian moves here and there, but they'll be chaotic and haphazard. Trump spends too much time on the golf course to pay it much attention.
That's not to say he won't cause pain with his antics. Oh, yes, we will indeed see a lot of that. Take it on the chin.
I really don't think Trump is the "brains" behind it all. He is just a guy egotistical enough to go along with the plan. "Oh, I'll be like, President for life?" I like the sound of that!, people will have to do as I say, I am the law! No congress to stop me, no pesky judges pulling back what I do, no laws to get in my way, sounds great to me!, Oh I have to give the religious fundamentalists some stuff, like get rid of abortions, get rid of Trans and gays, Oh, yeah sure, whatever!"
The think tank are Steve Bannon, Roger Stone, Steve Miller and various other authors of Project 2025, also the Federalist Society etc. They are all in on have a right wing president for life, pushing aside congress and judiciary, even corrupting or getting rid of elections entirely, they want a theocracy, a white Christian society and the Billionaires get to keep wealth and not worry about taxes, laws, regulations or ethics (as long as the kowtow to Trump's ego, simple as pie)
They've been planning this for the entire Biden term, and now are hitting the ground running, implementing it, no doubt the have an aggressive schedule to keep to. The midterms are likely to see the Democrats take the House and the Senate, so they have to do stuff before then and stuff to ensure the House and Senate have no power by then.
