What should I use to bridge gap between wooden flooring and tiles

Hi I’m just wondering what is best to use to bridge this gap. Because of the sizing I’m wanting to put a wide grout around outside edge rather than spread tiles apart too much. Area is 1250mm wide and tiles are 200mm wide and because of pattern don’t want to have thick grout lines in between each tile.

My thinking is I should perhaps put either a silicone or caulk strip between wood and grouted tile edge to allow for any movement – or would it not matter to just have grout right up to the wooden edge. The base underneath the tiles is concrete as it was originally my fireplace hearth.

**I’ve just updated photos with a rough layout. Looks like I won’t be able to do thick border at front as not enough room – didn’t realise there was some framing under the pantry that I can’t go past so this governs how far back the tiles can go !

Still don’t want to spread tiles too far apart lengthwise though so would the gap either side be all good to fill with just the caulk – it’s going to be close to 20mm each side.**
