Would I use a table or, something else?

So I am trying to find an inserted (or cloned) model in the workspace and get it's children then, I'm trying to get a random child from that and using "MoveTo" move the players character that clicked the button to it. I keep getting errors because if I use some thing like this:

local SpawnModel = game.Workspace:WaitForChild("SpawnsForMap1" or "SpawnsForMap2"):GetChildren()
-- it always waits for the first model and never reads the next part

-- or use this, after disabling the script and re-enabling it with another script:

local SpawnModel = game.Workspace:findFirstChild("SpawnsForMap1" or "SpawnsForMap2"):GetChildren()

-- same issue for this one except it outputs an error because it's not waiting it's searching and returning it found nothing for a reason I'm stumped by

--Error: attempt to index a nil value

-- I know what this means but don't understand how I can fix it to make it look for a set of models and only that set and if it finds one model return that model's children so the rest of the script can function and move the player to a random brick

So, could anyone let me know what I can use here that allows me to search for a lot of models but once it finds one that exists it returns that to continue the rest of the script? I feel as though I may be close to an answer but I'm not exactly sure. Would using something like this work or, something completely different?:

local SpawnModel = repeat game.Workspace:FindFirstChild("MapSpawnsName1" or "MapSpawnsName2" ) until return

--Yes I know this doesn't work but I'm not sure what would...

Other:

local Maps = {"Map1","Map2" }
local SpawnPos
local found = false
while found == false do
local work = game.Workspace
for _, v in pairs (Maps) do
if found == false then
 if work:FindFirstChild(v) then
found = true
print (v)
wait()
SpawnPos = v:GetChildren()
            end
        end
    end
    wait()
end

--Error: attempt to call method 'GetChildren' (a nil value)
--I'm assuming somehow I need to iterate this so I recognizes it is a model or something?


--EDIT: Fixed the error by declaring that v = work:FindFirstChild(v) after actually finding it.

Thanks for any help!
