From what I can tell, it would be better for the newbies to mine their own Bitcoin. Just a small amount which is barely enough to try out a couple of transactions. For practice. Not only would they understand where Bitcoin comes from, but they would understand the advantages of Bitcoin over Fiat much more clearly, after having an in-depth introduction with practical decentralization.
Then there are testnets online, with which you can practice trading on an exchange. Deribit testnet being one of my favorites, although I have not used it for years now.
Bitcoin mining is hard; I mean very difficult. It would be an understatement to say that most people are familiar with the equipment used to build mining rigs.
Even if it's meant as a learning experience, the plan to mine for practice might be like building a car from scratch to get behind the wheel. Nonetheless, who am I to make a decision?
Put another way, "Don't just drive; build the car, the road, and the traffic lights too!" Despite the fact that it defies logic, I admire your faith in Bitcoin, and I admit that I am a little bit envious of your apparent familiarity with the crypto world. Right now, Bitcoin is your only choice.
