What sort of jobs are you hoping to be able to do, and how much do you want to spend? Unless you spend properly serious money, there is no one toolkit that will cover everything, so ideally you need to build up your own set of tools.
I'd suggest you start with:
A decent quality set of screwdrivers.
A socket set. 3/8" drive for most smaller jobs, 1/2" for heavier jobs e.g. removing wheel spindles. 1/4" drive sockets can useful for small fiddly jobs, but 3/8" will likely be your "go to" size on a bike.
A set of metric combination spanners
A set of metric allen keys
Long nose pliers
If you have minimal experience of working on cars or bikes then a torque wrench may also be a good idea.
Unfortunately by using Amazon you are missing out on the Halford Professional range which offer an excellent balance of price and quality, and a lot of the stuff on Amazon is cheap tat. In general avoid anything of "DIY" quality, this is usually means the cheapest and lowest quality stuff.
Of the stuff that Amazon sells, some decent brands are:
Bahco
Teng
Britool
Draper Expert (the cheap DIY range stuff is crap)
Kamasa (the stuff in the turquoise boxes or with turquoise handles is good, the other stuff is cheap generic crap)
Sealey (often overpriced for the level of quality, but reasonably good).
