TBH, staking will depend on the market conditions. Just sharing my experience with bake and cake which was staked for months and made huge profits. I bought cake at $9 and bake at $0.95 for staking and waited for bullish rally on both of those tokens. Eventually, those got bullish rally and cake returned me 4x and bake did 8x according to my exit point before starting of this correction market. So, you can buy two of these tokens for staking with own risks. Also, nft based games are getting more hypes/popularity, so it would be best for OP to play those games and start getting passive incomes. ATM, i'm playing cryptoblades which is giving huge return and hopefully trend will continue till the end of this year. 
"De-Fi" tokens is where the money is right now. Both BAKE and CAKE have seen a huge increase in demand since their inception. It would make sense to buy and "hodl" these tokens for even bigger rewards in the long run. Of course, we cannot ignore the risks involved when investing into highly-volatile crypto tokens. It's a Russian roulette where you can either become rich or poor in an instant. It's much safer to invest into PoS cryptocurrencies than a "De-Fi" token because the risks of loss are low. Depending on market conditions, will be the type of cryptocurrency to invest for long term profits.
As far as NFTs go, I don't think it's a good idea to rely on them as a serious long-term investment. That's because not every NFT will sell for big bucks. You'd be lucky if you sold a digital art or painting for millions of dollars (USD). Only NFTs used for gaming have a bright future. I'd stick with PoS coins as they're a much safer bet for endless profits. Just my thoughts
