I joined https://www.bogleheads.org/ which was also when I started learning about mutual funds
Bogle started the first index fund family (Vanguard), so there is an index fund bias with many there, but the forum has very knowledgeable people. (Full disclosure, I am busy, and use indexing myself, but not in Vanguard.)
You have managed to hit the best all-around choices on your first try.
The large difference is to learn to have the discipline to ride out the ups and downs of investing. In a recession, it is a gut punch to see your hard-earned investments drop. The losing segment says the whole market is rigged, screw this and lock in their losses by selling. When the market improves, highs are being clocked, these same are likely to forget their previous folly and buy in again. It is investing that is controlled by emotions, and is a buy high, sell low outcome. Mastering your emotions in investing is the key to investing. Many people give 1/4th of their money to brokers so that they will be reminded of the previous paragraph, when they need it most.
We are financially independent thanks to indexing, and using emotions in a constructive way. We also have been through a few ups and downturns, making money in each cycle, by riding it out, and asset allocation.
Follow your plan and ride things out, and you will likely be a multi-millionaire. It is not overnight, though.
Decimal fractions of a percent are low fee. Vanguard is mostly, if not completely, low fee.
