I guess I was thinking this was obvious, but in retrospect, I'll point out that all of these can be applied to partial selections, which can be useful when applied to a subset of columns or rows:
(done by selecting bottom half of each character, and applying GMIC Morphological-> Dilation - Original (Octagonal))
Maybe I should also explicitly explain that the abbreviations sq, circ, and oct refer to square, circular, and octagonal 'kernel shapes' for morphological operators. The kernel shapes effect exactly which pixels are affected by the morphological operator; for example,
at size 2, Octagon is the most suitable for applying an 'outline effect' via "Dilation - Original". This is because at size 2, it forms a diamond that perfectly 'borders' the central pixel.
This image illustrates the difference. The original pixel is marked in pink and affected pixels are marked in blue.

If you insist on being pessimistic about your own abilities, consider also being pessimistic about the accuracy of that pessimistic judgement.
