It actually sounds daunting at first but depending on your level of paranoia, you can get away with just a few hours of work to do a pretty good job of securing your crypto ecosystem.
My solution is Coinbase + Binance for exchanges, MetaMask for the immediate needs, Ledger for storage, and since I am a bit of a geek anyway, an air-gapped machine with offline transaction signing and cold wallets (not because I really have much to protect, but because it is good to learn how to be cautious).
The air-gapped machine works as follows: I took an old laptop that I stopped using some years ago, wiped it clean, installed Ubuntu twice (wiping the drive again in the middle - wasn't necessary, but I felt I made some errors the first time) from a clean USB. Never turned on the wifi or connected it in any other way to a network, installed anything I needed from a USB stick. And I transfer anything I need to/from it via a USB stick. You can go much further than this on paranoia, but this felt sufficient for my purposes.
If I had to do it again, I'd probably assemble a basic Arch Linux OS (but that's a couple of extra days of work).
If you skip the air-gapped machine, you'll be done in an afternoon max.
Overall, Ledger is good, but it is not the same thing as a proper cold wallet. I'd recommend the devs own wallets on the airgapped computers. I'd say, the rule of thumb is below $10,000 you should be fine with a Ledger only - and it is dead easy. Beyond, consider spending some time making proper cold wallets.
