I find it a big pain to align verts, selecting several doesn’t give you the opportunity to simply type in a value into transform. Here I want these verts to line up in X , but using the Transform box just gives the median, typing a value does nothing. There is perhaps some super long ‘shortcut’ key combo that I cannot remember OR…
…I vibe-coded an Add-On called Vert Tools that allows you to set selected verts to an numeric exact position. Either copy the code in the blue box below, save it to a text file, change the extension to .py then add it to Blender — OR click the link below to download a zip file and install it thru’ Blenders Add-on interface.

"""
Move Selected Verts to Position
================================
Blender add-on that adds a sidebar panel (N panel > "Vert Tools" tab)
letting you snap selected vertices to an exact X, Y, or Z coordinate.
HOW TO INSTALL:
1. Open Blender
2. Edit > Preferences > Add-ons > Install...
3. Select this .py file
4. Enable the add-on ("Move Verts to Position")
HOW TO USE:
1. Enter Edit Mode on a mesh (Tab)
2. Select the vertices you want to move
3. Open the N panel (press N) > "Vert Tools" tab
4. Type a value in the X / Y / or Z field
5. Click the corresponding "Set X / Y / Z" button
