An XYZ tile service provides tiles based on a URL template with values substituted in for Zoom Level and X and Y counts of the tile. They are (usually) limited to a fixed projection (usually EPSG:3857).
A WMS provides an image of the map using a set of key value pairs (KVP) to specify which layers, styles, projection and size to use. It is possible to ...

Here's one way to find a similar CRS to the one used for an existing map. Since your map has lat/long lines, you can make a GIS project with the same lines into different CRS's until you find one where the lines are curved and angled the same as in the image.
Create lat/long lines:
Use the grid tool to make a lat/long grid for this area (longitudes 23 E ...

Yes, with the plugin Change datasource, it's the easiest way to change the path of a layer in QGIS.
Copy the layer file (or multiples files in the case of a shapefile) into the new directory and then open your project and change the source with the plugin.

I don't believe qgis is able to process Google Earth cache file.
I advice you not to wast your time. Instead use SAS Planet alternative. It stores tiles locally as
file:///F:/Tiles/Topo/{z}/{x}/{y}.png
Then you may use TileLayer or MBTiles plugin.
I hope that helps.

Further testing:
The pixelation is replicable - it is caused when there is a non-zero rotation applied to the SVG label background, or to the label as a whole via Placement. However, on export to PDF the background symbol is sharp.
The resizing behaviour is not replicable. I made a new label from scratch using the same settings and SVG, and it works as ...

I'm not sure what's going wrong with your SVG symbol, but it's pretty simple to re-create a similar symbol using simple marker symbol levels. With simple markers, you can control the symbol size and stroke width using millimeters, points, pixels, meters at scale, map units, or inches.
Add three symbol levels:
Simple marker - line, 45 degree rotation. Shown ...

GDAL, when compiled with SpatiaLite, can use all the SpatiaLite functions http://www.gaia-gis.it/gaia-sins/spatialite-sql-latest.html including ST_SquareGrid
ST_SquareGrid
return a grid of square cells (having the edge length of size)
precisely covering the input Geometry. The returned Geometry will
usually be of the MultiPolygon type (a collection ...

If these are all line features, then:
Merge with the doors.
Dissolve all lines.
Convert lines to polygons.
Dissolve all polygons.
If there are any lines not actually touching, thus the won't create a closed polygon, you can first buffer all the line features by said tolerance, a few mm, and then:
Convert buffer result to line,
Steps 1-4 above.
Negative ...

You can use pandas and geopandas libraries. Install these in your existing qgis python environment or install conda (and then conda install geopandas).
import geopandas as gpd
import pandas as pd
from shapely.geometry import Point
import os
csvfile = '/home/bera/Downloads/Gridded_AgroMet_Data_Europe_ver2_0_sample2.csv'
out_shapefile_folder = '/home/bera/...

You open the .csv file ("add delimited text layer" - CRS : WGS 84 - X and Y being the longitude and latitude attributes).
You can save it as a shape file or any format if necessary.
In the Processing Toolbox you choose "split vector layer", as "unique ID Field" you choose "DAY" and the toolbox generates the awaited files ...
You're done ...
