Often I will copy graphs into PowerPoint and redraw them. I can then customize them. If I did more graphs I would probably learn special commands to adjust line thickness, font size, colors, and other features.
Redrawing in PowerPoint allows me to import into MSWord figures that might otherwise be marginally compatible. Odd graphics formats that work well in the parent software but are either distorted in Word or create problems in how fast word works when saving or updating a file.
You could do similar things in programs like Photoshop and save as a pdf or bitmap before importing. The problem here is that file sizes can get large if there are many figures.
It depends on your audience and the format of your report. For example, if using LaTeX to write the paper or talk, tikZ is often used, but if you are using PowerPoint then depending on the complexity of the graph you'd probably just make it with the tools in that software. If saving plots back and forth between packages take care not to lose too much information (e.g., if trying to import a pdf into Word, don't take a screen shot).
I strongly advocate for R, which is an open-source statistical programming language. It is not user-friendly in the sense that you need to code your analysis, but high quality online resources (https://www.datacamp.com/ ; https://swirlstats.com/ among others) are easily available.
Numerous blogs give example and guidelines to draw any types of plots. Check this https://www.r-graph-gallery.com/ for example of graphs with all codes and explanation provided.
As an alternative Tableau (https://www.tableau.com/) is a great tool to make complex and animated graphs in the most intuitive way possible.
I hope this is helpful and good luck with your work.
