Need advice & help on various wild goldenrod species

I am finding that over time there seem to be a number of goldenrod species planting themselves in my native plant gardens. I haven’t tried to ID them because I figure I need to catch them in bloom before I have any chance of figuring out what they are. But I know they send out aggressive rhizomes and spread into large patches if I don’t happen to notice them for a couple years. Even if they are native, they are sure weedy because I even see them growing in the rotting plant material collected alongside the curbs in the street. I think I am seeing at least 3 different species, including Tall Goldenrod (Solidago altissima), which I definitely don’t want because that stuff seems to kill anything that grows next to it. In fact, I don’t think I want any of them given how aggressive they are, but I have just under 1/2 acre in total and weeding is getting tough!!
Does anyone know what these species generally are? Do you know what happens if you just do a modest control effort, i.e. pull them up when you happen to see them, or even what happens if you do nothing? Am I eventually going to have pretty much nothing but goldenrod or is this kind of a pioneer species which will eventually get crowded out? Or maybe it will just be another species mixed in with a wide variety of other plant species…..I should be so lucky!
Although I have done a lot to fight this stuff, including spraying Round-Up on very large patches that accidentally escaped my attention, I am definitely getting the feeling that this is a battle that I am losing.
