ᐅ How can I repair damage to IKEA Hemnes furniture myself?

Good morning everyone, I have been using various IKEA Hemnes furniture pieces for several years now, mainly dressers and nightstands. Unfortunately, over time, some typical signs of wear and minor damage have appeared – including scratches on the surface, chipped corners from impacts, and in some places, hinges that have become slightly misaligned or loose. My question is: How can I effectively repair these Hemnes furniture damages myself without having to replace entire parts? Are there proven methods specifically suited for the MDF and solid wood fronts of Hemnes furniture, including advice on suitable wood glue, fillers for painted surfaces, and screws or replacement fittings? I would like to learn from your experiences how to maintain the value of my furniture without complicated restoration or professional help. I appreciate any kind of guidance, preferably with practical tips, tool usage, and possible pitfalls to avoid.
