I would like to fill the LCD as much as possible/biggest so it’s usable.

The only way I found so far is modifying the opt/retropie/configs/mame-mame4all/mame.cfg file;

[config]
artwork=yes
samples=yes
antialias=yes
translucency=yes
skiplines=0
skipcolumns=0
beam=1.0
flicker=0.0
gamma=1.0
frameskip=auto
ror=no
rol=no
flipx=no
flipy=no
samplerate=44200
volume=0
cheat=no
#vector_width=640
vector_width=480
#vector_height=480
vector_height=320

kioskmode=no
force_stereo=no
# Anti-alias the display?
display_smooth_stretch=yes
# Stretches to fill screen (ONLY if display_smooth_stretch is enabled)
display_smooth_stretch_full=yes
display_border=0
# display effect postprocessing: 0 none, 1 scanlines
display_effect=0
#Set a static resolution
#resolution=400×240
#resolution=480×320
resolution=320×250
#resolution=360×228
