The subset of words that are solutions is an internal data structure of the game. It is clearly cheating to refer to that list. If you are willing to examine the inside of the game's black box, the optimal strategy is to simply extract today's answer.

In the limit, if there was one day of Wordle left and you looked at what it was going to be and then told me that the optimal strategy of which words to guess is to just guess the solution as the first guess, that's cheating. Your "strategy" becomes a question of how well can you compress the list of solutions into the entropy allowed by how you chose to express your strategy, in this case "four 5-letter words" or somewhere between 20 and 94 bits of entropy[0].

[0] 4*5 assuming that 1 letter is one bit of entropy, which is a rule of thumb when you're compressing gigabytes of text to log2(26^(4*5)) if we just count the combinations of letters
