I can give you this:

import * as obsidian from 'obsidian';

const LANGUAGE_OPTIONS = [
    "bash",
    "c",
    "c++",
    "c#",
    "dart",
    "go",
    "hs",        // Haskell
    "java",
    "js",        // JavaScript
    "kt",        // Kotlin
    "lua",
    "objc",      // Objective-C
    "pl",        // Perl
    "php",
    "ps1",       // PowerShell
    "py",        // Python
    "r",
    "rb",        // Ruby
    "rs",        // Rust
    "scala",
    "swift",
    "ts"         // TypeScript
] as const;

class OptionModal extends obsidian.SuggestModal<string> {
    private resolvePromise: (value: string | null) => void;

    constructor(app: obsidian.App, private options: string[]) {
        super(app);
    }

    getSuggestions(query: string): string[] {
        return this.options.filter(option =>
            option.toLowerCase().includes(query.toLowerCase())
        );
    }

    renderSuggestion(value: string, el: HTMLElement): void {
        el.createEl("div", { text: value });
    }

    onChooseSuggestion(choice: string): void {
        this.resolvePromise(choice);
    }

    async openAndGetValue(): Promise<string | null> {
        return new Promise((resolve) => {
            this.resolvePromise = resolve;
            this.open();
        });
    }
}

const wrapWithTag = (selection: string, language: string): string => {
    const cursor = '←→';
    return `\`\`\`${language}\n${selection}${cursor}\n\`\`\``;
};

const insertCodeBlock = async (app: obsidian.App): Promise<void> => {
    const editor = app.workspace.activeLeaf?.view?.editor;
    if (!editor) return;

    const selection = editor.getSelection();

    const modal = new OptionModal(app, LANGUAGE_OPTIONS);
    const language = await modal.openAndGetValue();

    if (!language) return;

    const wrappedText = wrapWithTag(selection, language);
    editor.replaceSelection(wrappedText);

    const content = editor.getValue();
    const cursorPos = content.indexOf('←→');

    if (cursorPos !== -1) {
        const from = editor.offsetToPos(cursorPos);
        const to = editor.offsetToPos(cursorPos + 2);
        editor.replaceRange('', from, to);
        editor.setCursor(from);
    }
};

export class InsertCodeBlockPlugin extends obsidian.Plugin {
    async onload() {
        this.addCommand({
            id: 'insert-code-block',
            name: 'Insert Code Block',
            callback: () => insertCodeBlock(this.app)
        });
    }
}

export async function invoke(app: obsidian.App): Promise<void> {
    return insertCodeBlock(app);
}

Works on selection and no selection. Edit list of programming languages to your liking.
Save as ‘Insert-Code-Block.ts’. To be used with Codescript Toolkit. Shortcut can be bound to script.

Here’s some more potential useful info found on reddit:

Personally, I don’t see how saving 3-4 keystrokes is worth setting all of this up.
