> 1) Add XY coordinates at both the start and the end of lines in a shapefile (avoiding to create or extract a second point-shape of specific vertices).

You can extract specific vertices and then use the field calculator to get the coordinates 

https://docs.qgis.org/3.16/en/docs/user_manual/processing_algs/qgis/vectorgeometry.html#extract-specific-vertices

> 2) Extract the envelope or to poligonize just the border of a cloud of points(shapefile)... Similar to such with which do it from a raster in the GDAL Raster Conversion tool.

This can be done with a concave hull.  A better alternative are the boundary tools in Lastools.

> 3) Create 'string' or 'text' fields with much more than 4000 characters of width inside the shapes, not only 255.

I you use a file format like geopackage, you will not be limited to 255 like the shapefiles.
