While upgrading your RAM and storage can get you more performance out of your system, it won’t really help you run newer versions of the macOS.
There are different issues at play here! First Apple’s OS support is set to High Sierra 10.13.x as the highest. Thats not to say you can’t force newer OS’s using hacks! But there are limitations here as many of the benefits of the newer OS’s require hardware to support them! While Apple offered support for High Sierra I personally don’t recommend it on this series! Again the issue is hardware! Your system uses a SATA drive interface which is not as powerful as a PCI interface used in the Retina series. The file system was also altered to APFS starting with High Sierra when a SSD was present. Which is why you need to stick with Sierra as APFS is too chatty unlike HFS+
So unless you have something that requires a newer OS I would stick with Sierra or High Sierra if you must.
