I started out recently with the same idea as the OP but i have come to realise that this game isnt designed to be played as single person doing it by yourself, its very much an MMO. The problems presented were and are intended to be tackled by the whole community - you wont discover even 0.1% of the secrets by yourself - the idea is that someone out of thousands of players would discover something and they would spread the word to other commanders. Also, the game is 10 years old - a lots happened and a lot of discoveries have been made and shared already - thats why theres all the fan made collaboration sites. Theres a lot to catch up on to understand the current state of things. The game is deliberately vague as to whats going on and leaves the player to educate themselves - its a fascinating journey and the storytellers are the community. The lore isnt clearly laid out for you chronologically in the game, nor are the key discoveries - FDev didnt put tools in the game to track many things, perhaps because they knew it pushed people to interact and collaborate out of game, which is almost more remarkable
I would defo recommend new players watch Drew Wagar's (the ED author) Elite Dangerous Lore Introduction playlist on youtube to get a grounding in the universe as a start, and inara is fantastic for seeing / tracking your and other commanders activity around the universe and in the thargoid war, its a real hub of the community - you dont have to use it to find cheesy trade routes - its much more than that, its like a player made interactive encyclopedia. No one man can save the universe, we have to do it together
