You could try using the slider at the lower right in Sigil. I typically set it at 130%. Be aware that this may give the impression that the text has been set to bold, but it has not.
Font faces for the Sigil display can be set under preferences and you could use a larger face and one which is less cramped between words making the cursor more visible. Changing this does not alter the displayed text in the ereader, just allows you to choose whatever font is more pleasing to you.
