Select same, with multiple selectable attributes and customisations
When using the Select Same feature we need a lot more options, like all objects with the same transparency effect AND opacity AND tint AND line weight etc, that can be selected from a list of attributes. Same sort of list as the options list for the Eyedropper Tool (see screenshot).
It should be split into sections that allow vectors graphics selections as above, but also things like selecting all linked items that are the same file AND the same size AND rotation AND opacity.
Selecting all text in a certain colour, font, size, style so they can be updated en masse would help too (overlapping with another suggestion here).
You can then tick as many as you like before performing the select using your chosen filters. A preview mode would be useful too, so you can see what you're picking up.
Once set, selected filters should be saveable and accessable from a scrollable list alongside the filter window for instant selection without opening a save / load screen.
Finally, each select same filter window should have an option to add / subtract from the current selection, so selctions can be stacked / refined.
This would be a huge time-saver when updating many files with similar changes whether to update embedded elements, for corporate image updates or technical changes like minimum line thickness.
There is also FindReplace Art paid plugin that allows to do almost all of the features requested. Highly recommend to try it.

This would be a compellingly useful improvement to the UI.
Add to / Remove from selection would get much of the way, but being able to combine 'Same...' criteria with checkboxes or some such would be extremely useful. Basically a Selection Filter editor.
Other useful selection criteria:
In Layers below
In Layers above
Wider than... / Narrower than (some value)
Taller than / Shorter than (some value)
Font size greater than... / less than...
Bounding box / x,y outside artboard
x/y greater / less than (some value)
Overlaps objects/paths in current selection

This is a fantastic idea!
It doesn't do everything you've described, but there is a plugin that gives you more "Select Same" options and it's free. Find it here: https://rj-graffix.com/downloads/plugins/#selectmenu
