I recommend looking at the Integrain WoodBlend, Cabot's Wood Tone Putty and Timbermates Wood Filler.

Wood filler is intended for filling gaps, holes, and cracks in wood that is yet to be finished, and can be sanded and stained after it hardens. Wood putty is intended for filling minor gaps, holes, and cracks in wood items that are already finished and can't be sanded or stained.
Mixing Sawdust and Glue
To create this filler, collect sawdust from sanding the floor or from a similar species of wood. Mix the sawdust with wood glue until it forms a thick paste, then press the mixture into the gaps. Allow it to dry thoroughly before sanding the area smooth and applying a finish.
If you have sawdust from the same type of wood, you can mix it with wood glue to create a paste-like consistency. Apply the mixture to the damaged area and let it dry. Once dry, sand it down to create a smooth surface that blends in with the surrounding wood.
Yes – absolutely. Silicone caulk is effective for bonding and sealing wood surfaces. Its versatility ensures secure and durable adhesion and results in a long-lasting finish. Silicone caulk creates a flexible, robust barrier.
Acid-cure silicones work best on non-porous surfaces such as glass and glazed tile, but they can corrode metal and etch some plastics, whilst neutral-cure silicones work well on metal and wood. It's all about performance and silicone sealants are the reliable way to seal joints against the elements.
Let's clear up the confusion right now: Wood fillers can be sanded and stained and are best used on unfinished woodwork. Wood putty is best for repairing cracks and small holes on finished woodwork.

Caulk, sealants, expanding foam, backer rod, grout, and mortar are among the most commonly used substances for this purpose, offering versatility and durability in different contexts. When selecting the appropriate material for filling a particular gap, several factors must be taken into account.
For large gaps in kitchens or baths, use a backer rod to fill the gap before applying joint sealant. Backer rods fill the space and reduce the amount of sealant needed to fill the joint. They come in a variety of shapes and sizes, so measure the width of the joint and follow the recommended ratio size when purchasing.
Gorilla wood glue is some of the strongest wood glue in the world, and for many woodworkers, it is the only wood glue they trust. This PVA glue sets up in 20-30 minutes, depending on the temperature, and offers an almost permanent bond for any wood joint.

Silicone caulk does not accept paint; your paint will simply bead and fail to adhere to the surface. So if you are considering applying silicone caulk anywhere that is painted—which is most commonly the wooden surfaces in your home—you will be unable to touch up any of the paint in that area later.
Generally, silicone is most effective for small to medium-sized gaps, typically ranging from ⅛ inches to ½ inches. Attempting to seal large gaps with a single application may result in collapse or shrinkage. When facing wider gaps, epoxy-based sealants or specialized gap-filling products may be a better choice.

#1: CA GLUE AND ACTIVATOR
You simply layer in some glue, let it work its way to the bottom of the crack, spray the activator, let it harden, add another layer of glue, and repeat until you've built up above the surface of the wood. Simply sand it down and the crack is filled and it looks just like clear epoxy.
