As mentioned and recommended in the https://stackoverflow.com/a/2061547/15905792
One drawback to the ver function is that it only tells you what's installed, not what has an available license. It's possible to have a toolbox installed and no license to use it (or all the available licenses could be checked out by other users). A better choice is the license function, which (as you pointed out) requires a unique "feature string" for each toolbox.
The following code checks for licenses for the entire list above:
index = cellfun(@(f) license('test', f), featureStr);
availableFeatures = featureStr(logical(index));
and
index = cellfun(@(f) license('checkout', f), availableFeatures);
checkedOutFeatures = availableFeatures(logical(index));
Unrecognized function or variable 'featureStr'.
Unrecognized function or variable 'availableFeatures'.
How to correctly check available toolboxes and its available licenes?

Ran in:
featureStr={'MATLAB','Simulink'}
featureStr = 1x2 cell array
{'MATLAB'} {'Simulink'}
index = cellfun(@(f) license('test', f), featureStr)
index = 1×2
1 1
<mw-icon class=""></mw-icon>
<mw-icon class=""></mw-icon>
availableFeatures = featureStr(logical(index))
availableFeatures = 1x2 cell array
{'MATLAB'} {'Simulink'}
