There is a pretty nice example using BlendDataLibraries and a relative path in the API: docs.blender.org/api/current/bpy.types.BlendDataLibraries.html

Example script to append all objects named Cube... from a blend file called link_library.blend in the same folder as the script like the add-on directory (tested):

import bpy import os

# "//" prefix is a Blender specific identifier for the current blend file
#filepath = "//link_library.blend"
#abs_filepath = bpy.path.abspath(filepath) # returns the absolute path

# os.path.abspath(__file__) returns path to the script
filepath = os.path.join(os.path.dirname(os.path.abspath(__file__)), "link_library.blend")

# link all objects starting with 'Cube'
with bpy.data.libraries.load(filepath, link=False) as (data_from, data_to):
    data_to.objects = [name for name in data_from.objects if name.startswith("Cube")]

# link object to scene collection
for obj in data_to.objects:
    if obj is not None:
       bpy.context.collection.objects.link(obj)
