R9 5900HX is barely 10% faster than R7 5800H, also depends on chassis where it is used. With 1 lakh budget, I'll pick HP Omen with R7 5800H + 3060 for content creation for 110k or so. Some apps like Davinci resolve & Premier pro are dependent on GPU as well, so a 3060 vs 3050 is a bigger gap than R7 5800H vs R9 5900HX vs R7 6800H (don't get me wrong, CPU is still pulling the majority of the weight).
Maybe, just maybe, an i7 12700H + 3050 with a good cooling system might outperform Ryzen for content creation, but no data to back it up. So R7 5800H + 3060 is a very safe choice. Not many R7 6800H reviews out there, but generally expect like 10% uplift over 5800H.
Also, the expensive G15 has a good QHD panel, but cheaper one has a 45% NTSC coverage 1080p panel, bad for content creation. You need at least 72% NTSC panel, which is present on Omen:
