First of all, is this the best way to do this...as in is a shorter or improved code possible? Because if possible I would like the rows to automatically adjust depending on the content inside the boxes? My main problem is that I am having a problem with the `\textbf` text and its contents not remaining on the top (like the strengths and threats). Also, some lines are darker than others as there are 2 lines being joined together. How can I solve this please?

I am not sure if this qualifies for a real answer. Anyway, here is something based on the `nicematrix` package that may come close. Some comments are in order:
1. Both for the Ti*k*Z matrix and for the `nicematrix` approach in order to vertically center the texts in the first column and at the same time to top-align the other cells one needs to "know" the heights of the latter cells. This problem gets solved by nesting `tabular`s.
2. I added a couple of `enumitem` keys to style the itemize lists.

The same strategy can be used in a Ti*k*Z matrix, where we can put `tabular`s in the cells, too. This is a bit more efforts but it does not require recompilations and should work on older TeX installations as well as the arXiv. (I personally would use `nicematrix` if have access to an up-to-date installation.)
