I'd buy a gaming laptop as many gaming laptops these days can act as a professional laptop as well such as the Asus Zephyrus. Asus Zephyrus G15 has AMD 8 core CPU + 3060-3080 GPU with 8-10 hour battery life in normal day tasks but no webcam. Asus Zephyrus M16 has Intel 8 core CPU + 3060-3070 but has 7-8 or so hour battery life but also has a webcam. The RTX GPUs are lower powered ones on these thin and lights compared to the more thicker gaming laptops but still significantly more powerful than a Steam Deck.
There's others to choose from as well of course.
