The last/fourth Amazon link that you posted (https://www.amazon.com/female-connector-chassis-Quality-Shipping/dp/B01CWJ4DA4) seems to be a good buy at $6.49 with FREE shipping included. Shipping/handling can sometimes kill you on these small online purchases.
For VHF-Low and VHF-High, the SO-239/PL-259 chassis mount would be just fine with minimal loss and it is cheaper to purchase compared to the N-connector version. For UHF, 700, 800 and 900 I prefer the N connector as I think it is a better choice for those higher frequencies.
