You can't do all that much. The credit score is a number, so people think that having more of it is proportionally better. In practice, it acts as a threshold. It is more useful to think of it as "lendable" vs. "deadbeat".
Generally, there will be some low point (eg. 650) where if your credit score is not at least that much, you won't be getting any loans period. Sounds a bit arbitrary, but you only end up there if you are known not to pay off loans (ie. a deadbeat) or nobody knows whether you pay off loans because you haven't taken any. Above that, there is a small range where higher credit score means slightly lower interest rates and slightly better quality credit cards (eg. cashback and so on). These benefits top out at a high point (eg. 750) after which you don't get even better offers for having a higher score. You end up above that high point by simply paying off your loans on schedule as a reasonable person would. If you miss a payment here and there it won't change things that much, what matters is whether you are overall in control of your finances or not - people who are not in control tend to quickly ruin themselves and become unable to pay off any loans, rather than just some.
For a bank, ideally you would be a "lendable" person (>750 or whatever) which basically means that barring any unusual circumstance, you can be relied on to pay off your debts. They can determine the interest based mainly on business concerns (how much money they want to make, expenses, and so on). Below that, you get people who cannot be relied on to pay off the loan. Ordinarily, you would simply not lend to such a person, but a bank can squeeze some water from a stone by driving up the interest enough to cover defaults and delinquencies. But once you get people who are truly deadbeats, it is impossible to loan to them at any interest rate (there are legal limits on how much you can charge - these days you can't sell people into galley slavery to cover your losses). So it's not that having a high a score gives you better offers, it's that low scores give you worse offers. If you have good credit, you will get reasonably fair offers. If you have poor credit, you will get unfair offers, but that's okay in a sense because you are expected to possibly not pay it back at all. If you have terrible credit obviously you get no offers at all.
You can't easily monetize a very high score because most lenders are in it for a profit. They will never give you an offer where you win and they lose. You can make modest gains (3-5%) with credit cards that have cash back or statement credit. You can get a bit more by churning (serially signing up for high-range credit cards to abuse their introductory bonuses), but you still won't get rich from it. You can't convert a high score to something like a big mortgage or auto loan, because few lenders are stupid enough to lend purely based on your credit score. They will also look at your income and collateral. No matter how principled and disciplined you are, it is unlikely you can handle a loan with interest rates bigger than your income and net worth, for instance.
I would advise against trying to monetize your credit by "borrowing money". Even a mortgage will still have 3-4% annual interest, auto loans will be higher, credit cards will rarely be <10%. You will be losing a lot of money. You should take these loans only if you will actually gain something from it (credit cards have benefits, cars and houses may improve your quality of life), not purely because your credit score is high. Borrowing a large sum of money also incurs significant risk (cars can crash, houses can burn down, both can depreciate due to wear and market forces) which should be considered more carefully than looking at your credit score. If your credit score is very high, the most useful thing you can do is relax a bit and stop worrying about your credit.
The exception is if you have some bad (eg. high interest) loans from when you had poor credit. You might be able to convert these into better loans by refinancing.
